I really agree with Mixedgass.
You will get tired of this thing rather quickly.
This is more ore less the same laser i had as my first unit. I used it for 3-4 times, and ended ripping everything out of the box, and replace all the interior with a RGB-brick and a set of cheap galvos. Have been using that a lot more after the rebuildt.
My advice is to save up a little bit more, and buy a projector that can be used togheter with a computer. Just as Mixedgass are suggesting.
You are actually better off starting with a one color system with galvo scanners and ilda interface than the one you are asking for a group buy.
and remember....
when the laser arrives at your house, think safety. Showlasers are not toys in any way.
