So my PS3 keeps getting the YLOD, last night I did the hairdryer trick to temporarily fix it. Got my game disc out of it, backed up my gamesaves and deactivated the system. I plan to get a new PS3 in January when my next student loan comes in.

What is the cheapest (SLIM) model I can buy? The hard drive size doesn't matter cause I'll be using the 500GB drive out of my current one with it. I'm guessing the SLIMs have a much lower failure rate? Mine was a launch 60GB model.
