Welcome and good luck with the forum. I actually almost bought a medium format folder this morning. I was referred to it by another person here on APUG who has and uses one himself. They wanted more than I was willing to spend so maybe next time. Anyway David Goldfard is very Knowlegable you two would have a coomon link.
I, too, am smitten by medim format folders. I only have four. My favorite two are my Voightlander Perkeo 2s. I would be lost without them. I take them almost everywhere. I am always looking for new ones.
Which ones do you favour?
I hope you don't mind me sending you a PM - I would love to talk old folders with you.
