There are a number of places to get the equipment. You can get ASA stuff from
www.officialgear.com Also where I work some wear only 1 bag unless the grass is wet then we wear 2 bags to be able to hold more balls. I kinda prefer 2 since that gives you a place to store the extra stuff you might need during the game (extra balls, extra indicator, chapstick, line-up holder etc.) Also I can see why ASA (as far as I know) doesn't make gray ball bags with ASA on it. I think gray pants with a gray bag looks bad. JMHO, Dave
