the dewalt dry cut saw does cut fine, but it is harder to set up accurately because the base is just stamped sheet metal with a very inaccurate degree gauge for setting a perfect 90* angle, and the clamping arm tends to change the angle slightly if you're not careful. the point is that if you want it to be accurate, you have fuss with it a bit.

i currently own the dewalt, but if i had it to buy over again i would pick the makita or milwaukee.
