Good Evening, Jules,
Like Tom, I can only comment on the similar 670 model. His comment about the shutter noise is absolutely right; it's the only real drawback I know of. I haven't experienced the moisture problem, but I've mostly used my Fuji inside. Results with both B & W and color are extremely sharp. The presence of a "T" shutter setting is a handy feature for night shots.
As to price, I did a Buy It Now deal on E-Bay for $750 about a year ago; the camera counter indicated only 32 rolls of use, so it came in essentially new condition, and I regard it as a good deal. I haven't calculated the pound/dollar exchange amount, but the price you mention sounds very comparable.
