Kobalt CO2 Cylinders for Pneumatic Tools

About 2 years ago, I bought a Kobalt CO2 cylinder kit (the one that’s about the size of an average thermos bottle) w/ regulator from my local Lowe’s store. They were very good at replacing depleted cylinders at a reasonable price (y’know, like service stations will do for your propane tanks).

Well, I’ve misplaced the pressure regulator, so I called Lowe’s to see if I could buy the regulator apart from a full kit. The response? “We don’t carry that line of Kobalt products anymore.”

Shucks! Has anyone else had experience w/ this product? If so, does your Lowe’s still carry it? I realize I can get another regulator at amazon.com for about $75, and I’m willing to shell out that much. But without a place to trade in my depleted cylinders, there’s no point in going this route. Maybe I should start shopping around among paintballers; after all, they’ve gotta get their compressed gas from SOMEWHERE.

Any advice would be appreciated.
