Mark, Like a few of the others, I have seen Jeff's plane and flown with him on trips a few times...you are 100% correct - it's worth every cent!
If I was advising someone purchasing a 150 right now, I would try to steer him toward this aircraft. It's complete inside and out - looks and flies great. Like you, I have put at least that much into mine and it is not nearly as complete or updated as this one!
