I finally got a chance to check out the 12" Makita slider alongside the other contenders such as PC, Bosch, and DeWalt 718. The Makita wins hands down the title of most rigid assembly (and it slides almost as well as the new Bosch). The PC is the next best, the Dewalt I rate 3rd, and the Bosch is loosey-goosey--too much flex! That's a shame, because otherwise the Bosch looks well thought out, and it slides effortlessly. The Bosch , like the DeWalt has a drive belt.
