Thanks for all of your suggestions. I ended up getting a Ikonta 532 2 with a Novar 105/3.5 lens and a Prontor-SV shutter. I hesitated for a while on getting a "3-element lens" but figured I ought to use a 6x9 folder and decide whether I like the system, before I start shelling out the dough for a pricier model. (A Bessa 1 with Color-Skopar just sold on the 'bay for over three times what I paid for the Ikonta).
Now I'm awaiting it in the mail.
