OK. A C-Note. Not necessarily tough but . . .
First of all, I wouldn't recommend Best Buy unless you really like them. You will probably get a better deal from NewEgg.com. Within your price range there you have a choice of Kodak, Fujifilm, Olympus, and Nikon. You can't go wrong with any of those choices. And don't fret over minor differences, most of the cameras in this price range are all basically equivalent. BuyDig.com is also another reputable source. I buy a lot of electronics from both places and have never had a problem.
I would only say be very careful about eBay. Yes, there are deals to be had. And just about as many ripoffs, probably more of the latter. Especially when it comes to cameras.
