Can't answer your question but I was looking at fotoman too a while back. From what I read, the built quality is really good. It's even got a brief mentioned in Lee Frost's pano book and commended for its 'any lens also can' versatility.
But after comparing price vs features, I went with Gaoersi instead. Fotoman although China-made is pitched at first world market with first world prices. It's cheaper than your horseman/linhof of course but I got Goersi for a fraction of the price with more accessories and feature than fotoman.
Anyways.. slap on one of those german LF format lens on anything.. picture sure kao wan :bsmilie:
