NPD's is excellent. You want the repro of the original rubber plaid mat. It's about 95% accurate which will be the best you will ever get. I put it over my original mat which was in good shape, but had some stains and minor wear spots...which is what I suggest anyone do. Don't throw away your original mat unless it is really trashed. Clean it up as best you can and keep it under your new repro... +1. Charles had originally suggested the idea..and I liked it.
