Wow, thanks for all the replies.

After days of thought I still don't know what to do. My wife could care less about flying, so she has no burning passion for it like me, and would prefer no to spend all of "our" money a toy... So as a family matter I am sorta in it alone. I don't want her/me to resent each other because of a plane, although I don't think that would happen.

Some factors entering in to my decsisons are:
- My daughter will enter college in 9 years, ouch!
- My retirement is being marginally funded at this point, ouch!
- Any major financial setback with health/car/house, etc. will bring me into deficit spending.

My wife reminded me of one of my favorite sayings last night. It's the one where I say that the last of the great deals, is the never the last. Deals are always out there, you just need to look... This is making me think that I should let this deal pass...

Now the other voice in my head says, "I have been looking for over a year and this is by far the best plane I have seen, BUY IT!" I could always sell it if it became a problem. I could get a partnership to help share the costs. This is something that I have thought about for something like 30 years. I have been frugal long enough, and it's time to get into debt American Style...

Help! I have been stalling the owner for a few days and need to act, or let him move on to the next buyer.
