Advice on first laser build

Finally, the funds are clear and the parts can be bought! I have already purchased the geeks.com drive and a aizix module. I have no clue what to do for the host right now. I know I want a flashlight style. The kryton looks incredible, but expensive and its not ready yet. For the driver, Im probably gonna get the lavadrive.

Another question, Is heatsinking an issue with these?

I'm going to use a leadlight. They make nice and easy hosts. Look around to see all of the cool LEDs and flashlights people have used though.
