I bought this set and it has served me well. The two mats are nice because I like to make both styles with rice on inside or outside so I cover one with plastic wrap and leave the other uncovered.

Another bit of unsolicited advice but I have been impressed with how my rice turns out when I follow the instructions in Sushi for Dummies. It is a nice starter book.

I don't have easy access to an asian market but I have found that between Wal-mart and the Meijer's store the next town over, I can get most of what I need. It took a while but my local wal-mart started selling sushi rice.
