If you want an honest vendor that's not going to try and rob you blind, order from http://www.bhphotovideo.com
Their sales staff doesn't even work on commission.
They've got fair prices on cameras and accessories, with a 7 Day return policy on Digtal Cameras with no restocking fees (make sure to read their policies as some restrictions apply).
If you want to save a few bucks, try http://www.buydig.com (a.k.a., http://www.beachcamera.com ). But, make sure to check with B&H first (as they often have prices just as good on some items).
Buydig/Beach won't have the same restocking policies (so make sure you know what you want if you don't want a restocking fee), and their accessories are higher (often selling no name memory cards versus brand name cards). I'd personally avoid their packages, too (that's probably how they manage to make a profit).
But, the camera body prices are usually a bit lower, and they aren't going to try and actively rob you or sell you a gray market camera.
