Hi Neil, Fiber lasers are very cool for smallish lasers that can do lots of different materials. They are very controllable, and by changing the frequency and pulse width you can tune them for the material you're cutting. Price is about triple what you've been quoted for what is probably a YAG. But I have no idea about cutting acrylics.
