What were the two you already looked at and didn't have interest in?
Antec makes a cooler, but I can't say how suitable it is for lap use as opposed to being on a desk.http://tinyurl.com/3f8lw
Both of the one's i'd thought about buying were made of plastic, one was angled with two 80mm x 80mm exposed fans beneath the other was literally three smaller fans built into a flat plastic enclosure, cannot really think how best to describe them other than that. They were approximately $30.00 each and neither seemed to be worth the money (in my opinion), perhaps I just need to shop around.
Shall check out the Antec one though.
