Wolf,
If you don't mind shooting film, you can afford a really good manual focus SLR right now. Film SLR's, especially manual film cameras like the old Pentax K-1000 and similar knockoffs, often sell for a few bucks on the used market, and many older Pentax lenses sell for a song. I sold two Pentax K-1000 type cameras and a half dozen lenses about two years ago. I made $70.

A K-1000 type camera with a 50mm lens and some cheap extension tubes makes a great macro lens.

Even some dSLRs are getting really cheap on the used market. The problem there is that, at least with Canon, the lenses are still just as expensive as always.
