I have been thinking about buying one of the 645 Fuji's but worried about reliability. It seems that they either have bellows problems or electronic problems and with some costing as much as $1000 it just seems like it's too much of a gamble for me. I did have a GA 645 for about a week and it took great pictures, but I thought the auto focus was slow and loud and the aperture dial was jumping and I guess it's common but at $950 I returned it. The GS645 pro and the GS645W seem to get somewhat good reviews but are they reliable? I like the size of these cameras. Any thoughts?
