This might not work, but when my cousin's PS3 died just a month after his Warranty expired they found that because of they used Credit Card-X (I don't honestly know which one), they got a free extended-warranty on their PS3 for something like a year. I dunno, if it's only 3 days-dead it might be worth a look into.
Myself I have a gaming PC/PS3 combo so I generally get titles from both consoles, but go with whatever console has (in your opinion) the better games since they're about the same in price anyways. If you've already got a fairly large sized 360 library, you might want to stick with that.
