I was looking through KEH's used catalog and wandered over to the Rollei section. It seems like there are plenty of different kinds of TLRs. For the best bang for your buck, which would you recommend? Parts availability and ease of finding a repair service are 2 things that really concern me. BTW, I will be doing landscapes and candid portraits almost equally, so a fast lens would be nice! Also, do TLR's have the ability to switch to different films rapidly? I know cameras that use the "back system" can have back changed fairly easily, but I am not sure how a TLR is setup. ANY TLR recommendations would be appreciated, though Rollei seems to be a favorite! Thanks again for helping me out guys, I truly appreciate it! BTW, my budget is around the $1000 range, though I'd like to spend roughly half of that to perhaps fund some other things. $300-500 seems ideal!
