Hmm I'd have considered getting that... favourite search now set up. My current plan is to attach a laser to my router, but on a second gantry. Since I'm using rotating ballnuts, I can easily have two gantries running independently on the machine, so one lightweight one for laser cutter (+3d printer) and a robust gantry for conventional cutting. The one you've got says 21m/min, which is manageable and I should be able to do it without loosing much, if any travel.

I expect to see your mayan calender on Monday...
