Well I will say one more thing and then shut up: don't rush into this. Extreme caution is the only way to proceed on a 55-year old beat-up Apache. Think about it in a worst case scenario for one minute- if this thing goes belly up on you, the chances of your being able to revive it are problematic, and may even threaten your airline career aspirations if you are in the same boat as most of us. Pre-buy excitement is your mortal enemy with these airplanes. I would get not one but two mechanics to go over it during pre-buy, and have them do it separately so they do not influence one another. Pay them by the hour and be more than happy to keep them working for a bit. Ask them to tell you why you should buy this airplane, rather than why not to. If all they can come up with is minor stuff then consider the buy and hope they did not miss anything crucial. I see these airplanes junked all the time because of things that do not even seem serious.
