Ryan, I am not the most knowledgeable airplane shopper, but I hear $79k is the low end buy-in on a maintenance complete L-39 today. I would be more nervous about the hourly operating cost than anything else. You are talking what, a grand an hour to fly one even after your checkout for insurance. It's not an airplane for individuals who have limits on income. A seriously successful trial attorney (John Edwards, etc.) might be able to afford one, but for most of us it is really out of the question. One flight school I know of offers an L-39 by the hour and they have an instructor for it, Western Air at BroomField, CO. Personally, I think I would rather just buy an old WWII piston warbird and be happy with the high g-limits.
