i will be using a 650nm laser module with i driver set to 420ma from hightechdealz but i would like to know what the easiest casing to use and a matching heatsink. I recently bought a WL E3 violet and am only slightly satisfied with it due to the fact that it wont burn much, less in fact than the executive series green laser i got from them a few yeas ago. but yeah looking for a good casing and matching heatsink
