Nah...don't need a wet-saw!
I used a Dewalt Model-DW703 Miter Saw with a 60tooth Triple-Chip Craftsman Blade to cut the 80/20 for my frame. Cut through it like it was butter! No burrs, very smooth finish.
Best part is, after cutting all your 80/20 you are left with an excellent saw that will last you a lifetime.
