Since you already have a Xbox 360 and price is an issue, I'll have to recommend the PS2. Many of the stuff that you can find on the PS3 are already on the 360 and in most cases, they are better on the 360. Also, although the recent firmware has alleviated the problems somewhat, PS2 games still look better on a PS2 than on a PS3. You should also try out Resistance before making a decision. Many people here love Resistance but it's not a system seller for me. If I had known how much I would have liked Resistance then I definitely would have waited until MGS4 is released before buying a PS3.
