I finally got my check to be able to buy one of these things, none of my local best buys carry the standards or professionals... I've looked around but don't know where else I can buy them in store. I saw amazon.com but it wouldn't be here for a few days and I'm going to be out of town the week and back to work. Why is it only available online? You'd figure you'd be able to buy one of these at target, walmart, radioshack, or a random place like Sears.
