    How big is that one on Ebay? I don't see any specs. Also - if you click on Shipping -- it says "free shipping" then it says "$300 shipping" Which is it?

      > Engraving Area: 12x8inches/300x200mm > Free shipping Standard Shipping (UPS Ground) > US $300.00 One-day Shipping (UPS Next Day Air®) Come on man, it says right there.

  Just search 40w laser engraver on ebay and you should get several hits around $400. Mine is working great after some mods. Mods: ~$25 for 8ft ground rod and wire ~ $35 for 24V DC power supply( includes 5 volt supply because I blow out the DC section of the board it come with) ~ $45 Raspberry Pi CNC Board + drivers ~ $35 Raspberry PI I can scp dxf files to the raspberry then rdp or ssh -X to open bCNC. Open the file and click Run. bCNC just added laser support so the setup is trivial. I'm not too sure on the cutting power though. I have done paper, leather and cardboard but the 1/8in plywood I have tried is too thick. I also had to put a 3904 transistor and a resistor in the board to make the laser on signal be sinking.
