I too like Nikon. The D50 is a good choice for the budget you are on. I would suggest checking a local camera shop first (not Ritz, Wolf, or TCI). I have found having a working relationship with a shop helps when things need fixin'. Amazon won't be of much help there.

But if you are set on an internet purchase, look at B&H Photo. There prices are usually very good. If you call them, you might be able to get even lower.
