I go mine at Indy Trading Post, 2851 Madison Ave, Indianapolis, IN 46225. that on South Madison old building on West side across from McDonald's
I suggest you call to see if they still have them, 317-782-4867, I was there last Friday, but the mat was not what I was looking for then, so I did not notice if they still had some. I bought mine at a reasonable price a couple of months ago.
If anyone is still looking for one, I found them at Bradis II (located behind Bradis) in Camby.
They had a whole stack of 'em, and they were selling for $10 each.
Glad to hear they're available around town for reasonable prices. I picked mine up along with an order I placed on Midway(?) a couple of years ago. Great little mats, I keep mine on my toolbox at work.
