An alternative would be to get a PS3 if you don't already own one. It's still pricey, but it could be nice to use it as an opportunity to play the exclusive games tou've been missing out on. Plus it's not likely to break down on you like an old 360 might.
Disclaimer: I still prefer the 360 to the PS3 overall, but PS3's are cheaper and you can try new, different things so it doesn't feel like a total waste.
