Hi Tom,
Welcome to APUG.
But watch it–– medium format is a gateway drug. Soon you'll be trolling the classified for 4x5 field cameras and then it will be 8x10, trying to jury-rig a hand held for street photos. You will, of course, eventually have to stop somewhere... and when you find where that somewhere is, tell me, I haven't found it yet. I'm still buying gear.
