I'd recommend either of the SteelSeries QcK models. I have one (the ordinary one) and I personally think it's fantastic. It's a bit hard to clean, but it's washable, so it shouldn't be too much of a worry.
I'd likely go for the thicker one if I had to do it over. Not that the QcK is uncomfortable - it isn't - but it's not really super-comfortable either.
Mousepads have no special "Technology" behind them, it's just a piece of fabrick stuck to a piece of rubber most of the time. Other times it's a piece of sandblasted aluminum, anyways i'd reccomend going to your local electronics store and getting cheap nobrand pads, because there really isnt a difference in what you get, except form factor and wether it's a hard or soft surface (If you do decide to go cheap , I'd suggest going for soft surfaces, since hard ones can have design flaws)
