Just got mine for $36.99 on ebay. I wasn't gonna get it either, but I saw it was ending soon so I said what the hell. I just made sure I didn't go over $50.00. I wasn't paying more for something I knew I could easily get for $50.00.
Should be here by weekend. But seeing I also got the new R&C as well as Dead Space at the same time (and have the GOW3 demo) I think my time will be devoted elsewhere for the most part.
