good stand or something like this to use macbook pro on my lap

[Sossity]

are there any good stands or trays that will provide a flat surface for my laptop when I am using it on my lap or sitting at it?

I like to use a lap desk for when I am using mine on my lap. They have a flat surface with pads to set on your lap, and mine has a wrist rest, which is nice to avoid the harsh edges of the MBP. I picked mine up at best buy for about 30 bucks.
