Mamiya TLR webpage
Take a look at:
I have both the Mamiya TLR (C220) with 6 of the 7 focal lengths they ever made - bargains are out there. I have a paramender, but have used it only occasionally. In a pinch, if afraid of parallex, just back up a bit and the neg is big enough to crop slightly and take care of the parallex.
I also have Kowa Sixes.
I have waist level and eye level finders for both.
It's all good, if it meets your needs. I know that doesn't answer the issue, but buying a camera is actually a pretty personal thing. Anyway, check Patterson's website for data on the TLR's
