No Nikon, they're clumsy and write SLOW. Grad, buy a Canon. Either one of the Elphs or PowerShots, doesn't really matter. They accept industry standard/vendor neutral memory formats, should you ever decide to print photos at home, their photo printers are actually very good and super cheap, and Canon will back their cameras with accessories for years after the camera has been discontinued. Also, the PowerShots (now) use standard AAs, so you can quickly swap in your own rechargeable NiMHs instead of having a built in solid battery pack that's not accessible on-the-go.
I would not buy a camera on eBay, personally. Circuit City and Best Buy are competitive enough as it is that you'll probably find something guaranteed NIB at the brick-and-mortar at an eBay price, you won't get stuck eating $30 in shipping, and you'll have somewhere to exchange it if its broken. Amazon would also be a good bet, as their shipping is more inline with actual packaging cost, and their prices normally best eBay average. I see Amazon has a Canon A550 listed now for <$150, and that's a great camera. The A560 is only $10 more, and that one includes the DIGIC-III processor, which has superior stabilization, red-eye reduction, and corner-blur correction. The A560 for ~$160 is an absolute steal.
