I had a Gaoersi for a little bit, kind of regret selling it now. They feel like they were built by a blacksmith more than a camera company, but what you get for your money is actually very impressive. Image quality will of course depend on the lens you put on it, and I do wonder about film flatness, but it's probably fine.
I now have a Fotoman 69, which is more graceful affair, although the actual Fotoman bit is only a bit of metal and a focusing cone, the rest of it is Horseman for backs, Schneider for the lens, Copal for the shutter, Leica for the finder. I would not hesitate to buy another Fotoman though, the dMini looks lovely.
