I personally bought a Maxtor 250GB ($60 after rebate) and have had no issues. It has only been install for 6 months, but in that time it has worked great. It's only downfall, and this is a big one in my computer, is that it is freaking LOUD!. It is soooo much louder than my WD 40GB, WD 120GB, and Seagate 200GB drives. I can only hear those if I put my ear up next to the case and then only when I have my fans at 8 volts or lower. The Maxtor can be heard no matter what.
Still, I can't complain because I got a darn good price on it. If there is not much difference in price I would get a WD or Seagate, but if it is a bargain then go for it.
