If you want the best quality go here.

The owner sent me one of his 4x6 DIY kits. They are super high quality but the size is too big and ugly. I emailed back and forth with him a few times on a new smaller design. It is very similar to a PSA/SGC slabs dimensions only thinner. I though he was going to do it but I have not heard from him or do I see it available on the site.
