It is my understanding that Fein blades will fit the Dremel and Bosch as well. I have no idea if they are worth twice the price but it seemed to me that in the cutting of wood the Dremel wasn't like in the ads for the Fein. It seemed slower and the blade did seem to dull faster than I'd like..not that that makes anything. There's so much I'd like that doesn't come to fruition.
