Like the tittle says I want to get another 360 after three died on me but I want the new 65 chip.

I live way in the mountans and it takes me at least an hour and a half to get to a walmart, gamestop, or bestbuy.
Are these new 360s in stores now? And, if they are, can I check the date on the back to make sure I get the new ones.

Does any one know of a on-line source that will guarantee a new one?
