I think I speak for 50% of members here when I say we've purchased things from dealers at least once or twice that were "off" compared to their photos...
My advice, and take it or leave it, is to stick to the member trade areas here on the board...that way you can ask for "live" pictures and be sure you're getting a watch with a working movement, etc. Also, you've got the power of the membership on the boards... people are less likely to post misleading pictures and have shipping issues, etc...especially if you buy from established members...
