I want a small machine shop tool that can rough cut aluminum or brass extrusions to size for a milling machine.

Space is a big factor in this, then price follows.

I am looking at the Rockwell Bladerunner, see:

Shop ROCKWELL BladeRunner 110-Volt Cutting Saw with Wall Mount at Lowes.com

Is it any good for cutting 2-3" thick aluminum extrusions (maybe 4" wide max)?

Do you have any other suggestions? I like the form factor of the bladerunner. Conventional metalcutting bandsaws are too big and bulky.
