I would guess the OP has made a decision by now, but if not, or for subsequent readers, I can also vouch for the Yashica MAT 124 G. I used one many years ago and loved it. I would guess some of the earlier Yashicas were good photo takers as well. It was nice having both 35mm and MF on an outing, during travels in Korea. There were times I felt the larger negative was a must, and the photos usually bore that out.
Some have already suggested MF folders. Unless you are stuck on TLR, there are certainly some very good folders out there. These days I am more inclined to take one of my MF folders than any of the TLR I have. Any of the better folders will give you great photos. I really like Welta, and my 6x9 Zeiss Ikon is very light, has even more negative real estate, and the lens is very good. You might want to consider that as they are much lighter and smaller than TLR, but are still MF.
