I have the HD Ryobi. It's great as long as you use the lithium battery. If they're still selling them with NiMH batteries, factor a battery change into the cost. I used it for my snow tires this morning, and in the past, I used it for a complete rebuild of the rear suspension. It's exceeded my expectations, especially given the reasonable price. I also have other Ryobi tools which use the same batteries...drill/driver, circular saw, even a flashlight. Once you make your choice, you're pretty much committed to the manufacturer's system for all your tools.
