I really like the edge lit acrylic signs I'm seeing here and would like to know what sort of laser cutter can do these. I'd like to be able to cut through 3mm clear cast acrylic, as well as etch it. I've been looking around, reading a lot, and I know the K40 machines are too involved for my hobby use - are there other, maybe simpler laser cutters or other machines that could do what I want?

Update - I bought a 40W C02 laser cutter, fingers are crossed. Thanks for the comments, they helped me make up my mind
