I'd be really interested to see what people are using, what features they have and if you would recommend it: laser cutting guide? Guillotine vs. trimmer? Magnetic arm? etc.
I use a Kaisercutter. It does the job, but sometimes when I have a large amount of cutting I wonder if I should get something more industrial that can cut several sheets of cardstock at once (as long as it doesn't ruin alignment!), maybe with a laser guide, or magnetic arm.
What do you think?
