Right, VF. Good advice for anyone with these, really.
Such things are sort of distant on the radar for me just now, but I've been curious for the future. If it's about something important, I'll try and obtain one someone can vouch for, even if it costs more. I suppose it's also possible I might take a chance on a real bargain sometime if I ever get caught up on the repair projects I already have backed up, and something tempting-for-a-lark comes my way.
I've been wondering about them since I was doing the shopping that ended me up with this old Mamiya, but I wasn't too inclined to try anything too risky or unfamiliar then.
