I sympathize with you since I went through the same deal you are going through before I bought my 8x10. I found everything inexpensive was too big a compromise for me in one way or another. I ended up buying a used Wehman for $1,500.00. To pay for the 8x10 camera, lenses, film holders, etc. I had to sell my 2 Contax 35mm cameras with 5 Zeiss lenses which I had owned since the 1980's plus my Mamiya RZ67 and 3 lens kit.
What do they say, no pain no gain?
I see...I'm thinking of doing something somewhat similar anyways. I have too many cameras that I don't use: Leica/Nikon/Rollei.
