Yeah, if you have enough the right light and a tripod even the old Rebel XT (which you can get for dirt cheap) will do. Since it's for web, you don't need to shoot RAW. And since it's for web, you don't need an ultra high resolution camera. As long as you have a tripod, set your ISO 100 so you don't get any noise, and take your time to set it up, focus correctly, set your exposure correctly and you should have beautiful shots for not much money at all. The only thing fancy you might need is a polarizing filter to cut down on glare which I can see having with all those reflective metals.
