Thank you all very much.
When I say I am on a budget I mean I don't wish to spend more than $200-300 at this moment. I've already stretched my hobby budget by getting some lenses for my Canon F-1 and some darkroom equipment.
I like the idea of getting a TLR, probably some Yashica. I still need to read about other makes and models you recommended. I am not a big fan of getting a Pentax - they look to me like some over-sized 35mm cameras and I would prefer waist-level finder.
Also the square format of 6x6 appeals to me for some unexplainable subjective reason.
