I have the 6.5x9 version of the Soho and after a good clean up it works very well. I use a couple of Rada 6x9 roll film backs - though you do have to take care which lip will fit, and adapt if they don't. But with a new ground glass from Vist.lt in Lithuania, and a new front surface mirror from eBay's marty1107 in California (both very reasonable on pricing) it's quite (almost) a pleasure to use.
