Oh yeah for sure, they are incredibly useful. You can run paper through them and put a marker in place of the cutter to draw 1:1 scale plans up as well - perfect for guitar building.

I miss having easy access to them and all the vinyl off cuts at work. I see the odd one come up at pretty reasonable prices for a 600mm wide jobby.

My tool wish list is a little out of control at the moment though, when the $ and deals align I'm going to grab one.
