I got a brunswick 3 ball roller bag from K-mart for $35 plus tax. it is the best ball bag i have ever owned, and that includes some KR and other stuff.
In terms of price (other than the one from Kmart) you won't do much better than the streamline line from Storm, coming in at like $80 per. I've heard nothing bad about them from the people who i know that have em.

Bowling makes me feel stupid. I don't know of anything else I do that frustrates me so much that I want to quit. Yet there I am the next day, waiting to take a lickin from the 2-8-10.
