mini dorcy heat sinks and gb laser diode?

where can i get a heatsink that i have seen in kenoms tutorial about how to make out of a mini dorcy

also, i have been hearing about a GB of sony lasers, can someone tell me when it was, the specs, and the price that you got them for. i would like to buy one if someone is willing to sell

sales.stontek.org. You can't buy a spacer you have to go to a machine shop and have them make you one. Measure the inside of the head and the outside diameter of the module and your set. good luck.
