XBox 360 help

I am looking to buy an XBox 360 but I really don't want to because it's just a 3 year old computer. :\ Where's the cheapest I can buy one? Refurbished w/e.. etc. WORKING.

I don't want to pay 199.99 for something I can get cheaper. :\

360 fails get a ps3 free online game play and better games. Also they don't fuck up 4 weeks after you get them to. 360 is shit.

But I also want to get a 360 because of GTA IV: Stories... they might never come to PS3 but maybe PC because Microsoft signed an exclusive deal with Rockstar. I don't have a problem with buying online service.
