Black-Decker-HPD18AK-2-18-Volt-Performance

I have both this tool and the Rockwell Sonicrafter. Overall, I like the PC better simply because of the quick change blades. The chuck is well designed using a heavy, trigger actuated spring that locks the blades in place. So far, I have had no problems with blades slipping and I don't envision any.

The Sonicrafter is a well-made tool and seems fairly heavy duty. Mine has taken quite a beating. The only complaint I could have with it is the chuck, which requires removing and replacing an allen bolt in order to change blades. This can become tiresome, especially when you are working under very dusty conditions, when the dust can get into the bolt threads and make the bolt difficult to remove and tighten.

The PC has a tough plastic gear housing as opposed to the Sonicrafter's metal housing. I don't know what the gears are made out of in either tool, though both tools are about the same weight. The only other difference I notice is that the fan in the Sonicrafter seems to push more air than the PC's. In actual use I have not noticed that either tool runs cooler than the other. Both tools seem to cut at about the same speed. I haven't noticed any other differences.

Overall, I prefer using the PC because blade changes are so much faster.

UPDATE 11/30/11
Some people have mentioned that the Velcro on the sanding pad has a tendency to melt. This occurs with all brands of oscillating tools and is not unique to the PC. Here is a Youtube link for the Fein Multimaster which explains how to sand properly in order to avoid the problem. I hope this helps.Makita-9557PBX1-2-Inch-Grinder-Aluminum
