When I bought mine I happened to find it in stock at Tiffin Aire in Ohio. I seem to recall the price was a bit less than through Aircraft Spruce.
I wasn't shopping for best price, I was just trying to get it faster than the 30+ days I was being quoted by other places. However, it seemed to work out.
I just Googled the prop part number and found it that way, as many prop shops seem to advertise what they have in stock on their web-sites. Alternatively, you can just call any prop shops and see if they happen to have one and/or can get it faster/cheaper than Wag-Aero.
One extra tip - since I bought my prop from a prop shop and not direct for the manufacturer through an on-line store, I had the option of having it repainted to my liking. So I had them paint it white with red tips. In my opinion, it came out really nice compared to the stock grey with white tips. Even Tiffin Aire said they had customers notice it and ask if it was a composite prop.
Of course, with the extra painting the price went up a bit, but it was worth it to me. Here's my post on the subject (from ten years ago):
PS - as I re-read the above link I'm reminded that the first spinner didn't fit correctly (the holes were mis-drilled). The spinner is made for Sensenich by ACS, and the complete package isn't always test fit for accuracy. Something to ask before buying if possible.
I have a 1A100/MCM6950. It was pitched 48" when I bought the plane, but it was VERY short, so I had Maxwell re-pitch it to 50". The RPM is better now, but I suspect it performs about like a new 48", and is probably not very efficient, as it has been whittled down over the years, including rounded tips. I figure a new "L" series 69CK will be much more efficient.
Perchance did you notice any increase in cruise at the same RPM with the re-pitch?
The current prop on JBN is short too - though it sounds like yours is shorter. We do have a lightly used, freshly overhauled one to put on this spring, I'm hoping the extra 2" in length adds at least noticeable performance gains but also wonder if a re-pitch on the existing one would be beneficial.
I show around 2550 rpm during the initial climb @ 65 mph IAS (digital tach). Before the re-pitch it was more like 2630. In cruise I don't see the kind of speed that many others on this forum report, even with the 50" pitch, again because I think my prop is not very efficient.
I hope you guys post the performance results of the prop changes. For instance... Max static RPM, Climb RPM and Cruise Speed at (X) RPM... before and after.
I spent lots of time investigating propellers and performance before and after reworking Delmar's HCM. It would be neat to install and New Propeller on do same day performance checks.
Simply replacing our worn/whittled McCauley with another used, but fully dimensional, McCauley made a noticeable difference on our airplane. So, an apples to oranges comparison of replacing an old whittled McCauley with a brand new Sensenich doesn't really provide any real useful data when simply comparing MCCauley to Sensenich. It would be much more useful to compare a brand new McCauley to a brand new Sensenich.
If I were a betting man, I would wager that there wouldn't be much, if any, significant difference.................
My new 69CK arrived today! Will post a Pirep when I get it installed. The new Sensenich PMA'd spinner arrived the other day, and I had it painted at a local body shop. Looks real nice. A different shape and size from the Cessna spinner - that will take some getting used to.

You'll get guys asking where you got an STC for a constant-speed prop.
I got the new 69CK-0-48L prop hung today. The new Sensenich/ACS spinner looks quite a bit different and will take some getting used to. The spinner fit the bulkheads perfectly and all the holes lined up, but the propeller blade openings had to be massaged with a Dremel tool as there was some interference. One unforeseen issue is my cowl plugs no longer fit worth a damn.
The new 48" has exactly the same static RPM as my old 50" McCauley (2440). I have long suspected that the old 50" was probably performing about like a new 48" due to having been whittled down over the years, including rounded tips. With WOT at 2,500 MSL, RPM was exactly at redline (2,750).
If anyone can use my old spinner or propeller, let me know. I will make you a good deal on either or both. The spinner and bulkheads are in very good condition with no cracks (the rear bulkhead is fairly new). The prop was re-pitched, balanced and painted at Maxwell Propeller in Minneapolis in July 2013.
She does look different, Fred.......but it looks just fine, too.
Besides, spinners are just there so we have something to rub on and gently pat when we tell the plane "good job and thanks" when we walk away after a flight.

I'd rather pat on the head than the nose.
That might explain the shiny spot on the top of the cowling . . .

I was afraid I was the only one that did such a thing, I guess I'm not weird. 😎

Thanks, I am enjoying it. My impression is the plane climbs better now, but I believe I may have lost some airspeed. My theory is the smaller diameter of the new spinner has opened a larger area of the cowl intake, causing more aerodynamic drag.
