like which one doesnt break as easily etc.

thanks

I only have the fat one but it is been doing great and been through many moves and doing great

There are two types of slims: One with the old hardware and one with new hardware.

The old Hardware (70000 - 75000 series) has a bad habit of getting extremely hot if left on for extended periods. This won't damage your console unless of course you leave a game running while you are sleeping, thus it overheats and melts some of the internal hardware.

The new Hardware (77000 - 79000 series) fixed the overheating problem (it still gets warm, but doesn't damage the console as easily as before). The problem with these versions is that they utilize new hardware internally, which unfortunately won't play certain games up to par like other PS2 models, or won't even play them at all. All of the major tites work fine though. The list is on playstation.com.

Personally, I would wait for the 90000 series to come out this year if you are a compatibility fiend. They should be in the states by the spring, as they came out in Japan in November, and we usually get new PS2 hardware 6 months after them. I will be getting a 90000 series for a spare room in my house.

Fat one is more durable; a lot more durable. Mines taken a lot of beatings and still works fine (thank G-d). The slimline has an ethernet port right in it so it's easier for online play.
