I would never, ever, consider buying a torque wrench from them.
Back to the topic, buy one of those adapters shown above for a couple bucks and you can use any compressor.
Actually, HF torque wrenches work well, but are rarely calibrated out of the box. We used to buy them by the dozen at work, and while out of the box they varied by ±20%, once calibrated, they held well.
