Jeff,
It will be sad to see 73J move on but it makes sense to fly a machine that fits the mission. To bad it isn't a tailwheel.

Have you thought about a Hawk XP? A friend has one and it is a good mix between the 172 and a 182. It has a 190hp (I think) Continental engine. The only downside with the original engines is the 1200 TBO. He recently had a factory reman installed that brought the TBO up to 1800 hours though.
As Mike Marra mentioned, if you email a copy of your ad up here I'll print it out and post it at airports local to the Lehigh Valley area of Pennsylvania.
You still have the video we shot out in Clinton right?
