Speaking of celes or fat cats owning older fighter jets, I remember seeing a televison show about the topic. "Decommisioned" (if that's the right term) jets are brought over from Russian and gone over, then purchased (or purchased then gone over) by guys that can afford it. Like Joe said, the price hovered around $100K. One of the owners was the actor who plays Worf on the Enterprise series.
There was an article in one of the aviation magazines about this too, but I can't recall which one or how old the issue is. Apparently, there are a number of private citizens out there that own these older jets.
Joe, Michael or the numberous pilots here would know, but to fly a jet you need a lot of hours. So much so that when I take up flying, I may be well beyond a youthful age to be able to fly a jet...if I could ever afford one. So my fantasy of owning a jet was swept aside.
