A month or so ago I bought a Rockwell Sonicrafter, and can say that I am both impressed by and pleased with this tool. Makes cutting tabbing, plunge cutting, and cutting in tight spaces really, really easy, and puts out minimal dust. Took a few minutes to figure out how to best use it, but wasn't hard to do so - fairly intuitive. It does heat up pretty good when used for several minutes at a time (like on longer cuts), so be careful when changing blades or you can get smooth fingertips.
