There's another 6x17 rollfilm back on ebay right now from the company in Hong Kong. I have seen this before but am not terribly familiar. Anyone bought one? Was very curious about the company, its responsiveness, how you paid, how long to receive, and - of course - what about the back? Any good? I am assuming the Keith Canham's $1100.00 back as a sort of benchmark here. You comments greatly appreciated!
