A tale of a third POD publisher

My earlier post compared TheGameCrafter.com with SuperiorPOD.com.  There's also Artscow.com, another popular print-on-demand source for cards.  I haven't used them, but one customer has done a comparison here, and finds the quality of product from SuperiorPOD better.  Here's another customer with a photographic comparison showing that the SuperiorPOD cards are a good deal thicker than Artscow.
