Kiu,
You are right. My most expensive camera is the Spotmatic kit with 2 Super Takumar lenses, 1 Mamiya Sekor lens, all the hoods and cases for the lenses, and a black leather case that holds all of that stuff, it was 50.00 US. I since bought the Super Tak. 50mm F 1.4 from David Murphy here. None of the other cameras were over $30.00. My wife says I am cheap... I prefer to say frugal.
Speaking of F cameras, there is an F2 with standard lens and Nikkor F2.8 135mm tele. on auction now at shopgoodwill.com. The current bid is 224.00 and a day to go. They also are auctioning an F3. I would probably be looking for a nice Barnack style Canon RF or a Canon P if I was going to spend that amount. I like the style and size of the rangefinders. If I ever got to handle an F2 I might change my mind though.
