You can generally get some older ones pretty cheap...problem is that they have a TON of problems that are quite annoying to fix
This is true and, especially with the older ones, people who can service them are getting harder and harder to come by.
I own a `53 Seeburg jukebox. The thing is a peach. I had it in my old shop, and it's now being used at a friend's done over basement (really cool retro cellar - he a very pinball machine too). The guy I bought the jukebox from deals in pinball machines too. He had some pretty cool ones.
This is what my jukebox looks like
