....Girlfriend is looking at TLRs, is the C3 a good one to go for?....
I can vouch for the Mamiya C3 and the C33. Both are excellent. They're the favourite cameras I've ever used....along with the 35mm Olympus OM-1n. They are heavy though, and I like weighty metal-bodied cameras. But if your other-half would prefer something not as heavy, and is willing to sacrifice the ability to change lenses, then then maybe a Minolta Autocord or a Yashica-Mat might be the ticket.
