I bought one of these last Friday and it was delivered on Monday. Lots of fun to play with!
Fortunately for me, all the optics were still aligned when it arrived. Everything was in working order and the software is pretty good. Their printer driver makes sending jobs from Inkscape and CorelDRAW trivial.
One thing to note - if you get the deluxe version the power is controlled by the software, not the knob on the front. If you hit the test fire button on the control panel instead of the one in the software you'll get a 100% power firing which will likely ignite the thermal paper you're using to check alignment..... Just in case you didn't read the paper that comes with it.
