My second MF (past box, folders and Bantams) was a Super Press 23 which gives even bigger negatives. It just happened to be a rangefinder, but I was getting it for the large negative rather than a C330 I had on lay-a-way. I think you could get a good Universal or Press 23 (the later ones, not the highly rounded early ones, for what you would pay for a good Rolleiflex. That with a 100mm lens and 6x7 back.
Even if you got a Rolleiflex for a little less, you would have a camera with a good, well earned reputation, but it would not have interchangeable lenses or backs. The Mamiya Universal and Super Press 23 have that, as well as ground glass finders all but one of which take cut film holders.
Of course, you can get a Yashica, or Rolleicord, Konica, Tower, or many other old but still good TLR's, for less. They just don't interchange lenses, nor with the exception of the Rolleiflex, backs. They will be less expensive, with the Rolleicord and Yashica cameras being some more expensive.
I guess it depends on what you want. I have a Rolleiflex I just can't convince myself to take out when I have the Mamiya 23. I keep promising myself, but ... Someday I will, I promise.
Was it the large negative you were anticipating or just seeing a large viewfinder? They can be addictive. Oh, you will find any MF camera other than most folders, to be much heavier than the 35mm rangefinders usually talked about here.
Don't feel bad if that was your first time to look into a TLR. They are a revelation to those who have never done so. You look at a large view screen with both eyes no less! And you know your negative is also going to be that big. Wow! Oh, did you notice that the image was reversed horizontally? Oh well.
Hope I haven't pooh-poohed you enthusiasm too much. TLR's are nice. I had a Yashica MAT 124G before I got the Mamiya and I loved it. I would just caution you to examine what it is you want, then if there are better alternatives.
BTW, my Rolleiflex has a rangefinder prism so I guess I can use that here too?
