My latest tool purchase was this
generic-brand rotary tool (like Dremel). It's been my lifelong dream to own something like this. I received it for free in exchange for writing a review. It seems to be high quality, much better than I expected, but I haven't given it a rigorous test yet. It's only $40 for the whole kit. I think I'm going to grind my chain stay a bit to allow easier removal and replacement of my rear wheel.
