So to get a rectangular size advantage over 6x4.5 you have to jump up to 6x7... and that is a whole other world filled with rangerfinders and SLRS that are better kept firmly on a tripod.

The Bronica ETRSi is a good entry point because you can get it for a reasonable price and if you decide you want to upgrade you can sell it easily enough without taking too much of a hit.
Thanks Noble, I think I will go for a ETRSi, I found a couple which hopefully will stay at lower prices!
