I can recommend the Mamiya TLR 330 as I use one myself. Wonderful piece of kit. They are plentiful, and cheap, so take your time, there are plenty to pick from. One thing to keep in mind is that the 220 range do not have the coupled wind on and shutter cocking that the 330's have, and I think they have a winding knob instead of the folding crank of the 330. Good luck with the chase.
