I have a 14" Milwaukee dry saw and its been good. The key to blade life is the cut speed, they dull faster if you go slow like with a regular chop saw. Also cutting on a flat surface dulls them faster, if you were cutting a piece of 1/4 x 4 turn it on its edge in the vice so your cutting on the 1/4" side. Not the 4" flat. Also the blades can be sharpened just like a carbide toothed wood cutting blade.
