I would check http://nationalbowlingstore.com/  The site itself seems to be in the process of being redone, but they are some good people to deal with and are pretty competitive with pricing.  They carry a lot of Roto/Storm stuff and will ship UPS.  Only thing I didn't care for is the drilling- I didn't have the best layout choices after talking with them and going over my game.  That caused me to find a new driller and plug/redrill some of my current arsenal.
