I'm looking for recommendations for reliable adhesive sticker printing outfits - can anyone point me toward a solid company in the United States?  Two inch round stickers, one color, maybe printed on foil or something on cost. 

Thanks!

I have been very happy with the product from http://www.stickerguy.com/ and I have found it hard to beat the price. For more heavy duty vinyl stickers the samples I have seen from http://stickerobot.com/ are very nice, but I haven't used them yet.
