Low Cost Laser Cutters

With up to 4 watts of laser power, the Emblaser is comes as a kit for as low as $650.

For five times the cost, and with ten times the power, you can get a "hobby series" laser cutter from Full Spectrum Laser.

Of course consider if you really need or want a laser cutter, as knife printers such as the Silhouette can be easier to use and much cheaper while not melting the material you are working with.
