I got mine from a local woodworker. Maybe try to check if there's one near you? The advantage is you can pick what type of hardwood you want for the wrist rest.
I may look at the cost and check out price of a small piece of cut wood to see if it's worth going that route. I'd just probably go and do the sanding and other stuff myself though, since cost of labor usually gets to a point where I feel like doing it myself.
I think that's the better option. Unfortunately, I don't have any wood working skills or tools. I hope you get the wrist rest that you want soon, @NightOwl
Thanks. Yeah, when I was looking for a keyboard tray to keep my desk free of clutter I also had run into not being satisfied with the options out there with the length and width of them being short for the space I wanted for my keyboard and mouse pad. So ended up having to make my own. So do still have the material needed once I get a piece of wood cut.
