I bought a no Name tool similar to teh Bosch one and it sucked. The tool got hot, it vibrated much more and it was noisier, too.
The Bosch Tool is a nice Tool when laying Laminate flooring, building kitchens or furniture.
I see only limited use for shop/metalwork for it.
Oh, wait: Dremel sells a cordless one, which is a re-Badged Bosch one, so the tools should interchange. Dremel sells a nice Jigsaw blade holer that could be a nice tool for cutting out handles and liners.
