This is pretty cool. A guy decided that the price on laser cutters is stupidly expensive, and he could probably build his own machine, less than just the tax on a commercial machine. I figure this will be my next project after building the Mendel RepRap 3D printer.
The recent Epilog Laser Challenge at Instructables.com got me thinking about building a low cost CNC laser. The engraver they had as the prize had a list price of about $8,000. The income tax on that would be quite a lot. I thought a larger more powerful machine could easily be built for less than the amount you would have to pay for the tax. The Epilog Zing 16 is 30W with an area of 16" x 20". Try to beat that for less than $1,000. I understand that a huge part of what you get from Epilog is software, safety, support and a guarantee, so it is not a really fair challenge.
