I'm a definite noob to this. If you get lucky you can get into this cheaper than you think. I found mine on Marketplace for $50. It's probably a 5 or 10 watter. No markings on the machine anywhere and, naturally, no manual. I got it home and finished hooking it up (they hadn't even hooked up the laser). The wood to build the cabinet it's in was $17.50, exhaust fan, power panel, etc was about another $25.00. Now that I have time I need to hop back on it. I also bought a 60 watt diode laser for $120 on closeout, with the driver board an extra $7.50. The laser fired up on a test run before getting into the wire loom. I am using Lightburn.
