My current stereo setup cost me under $700. It consists of M22's and a Velodyne VLF810 I bought at www.etronics.com. I would highly recommend this system, but since you like slammin rock music like Tool, You may not need the midrange and may need more upper midbass slam. Otherwise, somehow come up with the little extra cash and get the M60s. They seem to be pretty impressive speakers that no one seems to be unhappy with.
I often listen to Metallica on DVD-A on my M22's in Stereo mode, and the M22's can still slam well without the sub. But I do not know if it will be enough for you or not.
