I just bought a Sony DSC-S75 from buydig.com. I found them on pricegrabber.com. I've shopped them before for a video camera. They have good prices for cameras but offer expensive peripherals. Also, once you order online you'll get a phone call to "confirm" your order. This is where you get the hard sell for accessories. If you read the comments from buyers I think you'll find them accurate.
Overall I think they're good to shop from, just keep in mind what accessories you need, and what a fair price is for the extras...
