We have both a 10" bigfoot, and a 16" makita. We love the Makita, but the bigfoot is just OK. It's a great concept, but poorly executed. It's just a skill 77 worm drive with an aftermarket base and blade guard to accomodate a 10" blade. The blade guard never retracts corectly, and always has to be done manually. The castings are rough. It's great to have a 4" depth of cut in a saw smaller than the big makita, which is pretty heavy. BTW, our makita is the older model with the aftermarket base from GNWW.
