I use a laptop pad, it's extremely cheap, flimsy, makes loud noises when it starts and half the time the fans don't work. I did buy it at Micro Center for 10 bucks though, so that's to be expected. I honestly don't know whether the more expensive models are worth it, but when I got my laptop I felt I needed one because Toshiba's have a rep for overheating.
And you know what the funny thing is? I didn't even know who it was made by but after a quick glance at it and an online search, I found it for 28 bucks at Walmart.com.
PS don't buy this one.

And you know what you can't tell from the picture? The usb wire that connects to your laptop is exposed (i actually taped all the excess wire to the back of the pad) on top of the fact that the slightest jolt will cause one of the fans to stop working, or for it to make this loud noise that sounds like something's broken for like 5 minutes.
