does anyone here have experience with teufel enlagers? the info on the net (and this forum too) is pretty sparse. as far as i know they are old, but indestructible. would buying one (rather cheap) make sense? also is a "teufel vg 9x12" capable of printing 4x5? the including negative carrier should go up to 14x14cm. should more than one condenser be included in the sale (like one for small formats and another one for larger)? and, finally, how does this enlarger handle multigrad filters?
