Well, you know me. If I wanted something like that, I'd just make it myself out of template plastic. Great idea, though.

I actually thought about making one out of some lined template plastic I bought for a workshop and never used.
The real one is made from static cling - I think.

I hate to admit it but I bought one of these -- or a very similar product -- a couple years ago and have never used it. I don't even remember why I bought it! The cost is pretty reasonable though so I would say Go For It.
