Beast wrist wrest are incredible. I use one at job and it fits me perfectly. It greatly improves my typing experience. But he seems less active recently, still worth sending him a pm.
The other good option would be Noko's leatherworks. They are wooden wrist wrest covered with leather. And they look amazing. So this is probably your other best option. I don't own one from Noko, but the reviews from people that do are very good.
