The lights are on
Personally I'm sticking with my CECHL01 fat PS3. The 1st slims seem to be pretty good, haven't heard too much about the super slims but having the BD lens exposed when you change discs just doesn't sit well with me. I would say your best bet is to get the same model I have if you can find one that you know for a fact has never had the YLOD. Then open her up, clean any/all dust from the insides, clean off the old thermal paste from the CPU/GPU & heat sinks, finally replace the thermal paste with a high grade one like AS5 or MX4. I did this to my PS3 & it has been running like a champ ever since. I played ME2 for almost 14 hrs straight last week & the fan never went above it's 2nd stage.
