Hey guys, i'm asking this on behalf on my fiancee. She want's a 6x4.5 camera with the following: Metered 'slr' type prism viewfinder Waist Finder (switchable with the prism) Good grip (the one that attaches to the side) Film backs (switchable backs, to change from color to B&W, not catriges). Around $400-$500. Any recommendations? Google comes up with a good number of options, some making the requirements, other's not so much (some are a complete package, with just the lens being changeable). If you can recommend something that has a built in grip, that's fine, but the changable waist finder/prism is very high on the list. The film backs, not as much. Thank you!
