Get it from Djinn at Gamer's Hideout in Cineleisure. He provides great service and if Warranty issues comes up, it'll be taken care of very quickly.

But please, get an original UN-MODDED console. You'll be missing the best part of the Xbox360, which is the LIVE! service if you get a modded one. Besides.... Djinn only deals with originals.

Well, my first Elite had problems with the disc tray. I sent it back to Djinn, wait about 2 months.... Lo-and-behold...... completely BRAND NEW FALCON set was ready for pickup.
Big ups for GH on that one too.
