Well, I've been considering buying a PS3 [used] lately. A few weeks ago, I was staying the night at my friend's house. He had a PS3, and up untill then, I had no real interest in getting one of them [mainly because they seemed like a fancy blu-ray player to me, and had nothing I really found all that special.] Well, he let me play FEAR 2 for it, and I was AMAZED. It has THE BEST graphics I have seen to date... That reaction doubled when I saw Uncharted... It was like a trip back to when I played Tomb Raider, but on HD steroids! I loved it. And Call of Duty 4 was pretty nice too... It looked good and was pretty fun. Plus, I like the whole idea of the controller being motion sensitive, though I didn't get to play anythng that really used it like the Wii does. =/ But, all in all, it looked pretty cool, and I kinda want one now. But, before I take a stroll down to the used games store to pick one of these bricks up, I have a few questions. First off, which model would be ideal to get? I mean, they've got the 20 GB, 60 GB, 80 GB, which one would be best? I mean, I know full well how much a gigabyte is and what the numbers mean, but how much space do you need and for what? Is it like the Xbox 360, where, I've found, you really only need a 20 GB hard drive if you don't download everything you can? Second, does hard drive space matter? I mean, can you replace the hard drive with a standard PC hard drive? I would like to mod this with a bigger hard drive I have lying around if possible [160 GB SATA 2.5" hard drive from an old laptop]. Would I be able to do this, and does anyone know how if so? Also. Anyone have anything to say as to durability? It seems like quite the beast of a brick, so it should, in theory, be quite solid. But what about the Blu-ray drive they've crammed in it? Any help with this would be most awesome.
