Stumbled across this Portable Tile Saw while looking online for something else. I got it yesterday, and cuts through G10/FR4 like creamy milk fat, and -straight-. lol.

Weighs -maybe- 10 lbs. Thought I'd share
Got mine from Lowes for 58 bucks. Even better (at least locally) if you buy -anything- from them you get a 10 dollar off coupon for purchases of 50 dollars or more.
Get some screws, get back in line, and it's yours for $48.
Do need to do it outside, and wear a mask. However, I didn't try the "wet" option, which I will next time. Given the almost-waterproof nature of GR10, it should dry fast and nearly eliminate all airborne glass particles. Who hoo.
Yes, small things like this are victories I cherish. LOL.
