Thanks for the tip. And yeah, $300/ball is a little much for me right now.
I emailed Bowlers Dream, which has them on their website. They're sold out and didn't sound too optimistic at getting any more.
I've emailed Columbia but have yet to hear anything from them. It's going to take actually calling them, I suspect. That's how I got my Roto Grip Winning Streak -- literally, I picked up the phone and called their president. I ended up getting routed through his secretary to some Storm guys down in Texas who were next to a Roto booth at a bowling show, and they shipped me one straight from the show floor.
