>>3686436>$1600they can easily be found for half that, I've had 3 and never payed more than $600.
Rollei is going up though, that's kinda a pisser, but Bronica, Mamiya, Yashica, and Pentax MF can all be quite affordable.
LF is dirt cheap right now. I picked up my crown graphic for $300, and lenses between $80-$250. Rail cameras regularly go for under $150.
