EDIT* I guess this one has a lense, the G2, which I have read is pretty good. but is very expensive. Any alternatives for cheaper?
2nd Edit* I guess the 2nd link has an included driver as well. It includes the 1.8A X-Drive and the 405-G-2 already installed. It is sold by DTR, which I have already been recommended to check out by another member, so I think it looks like an ok deal?
It looks like your found DTR's listings. His website has quite a few more options. The different diodes he sells as well as combinations can be found here. You can purchase it with the driver and a 3-element lens which is cheaper. The 3-Element isn't as good at burning as the G2 but it has less beam divergence.
