This is the one I bought:
https://www.amazon.com/gp/product/B00WJDQZFU/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
I'm not so concerned with it's burning ability but I'm in love with that solid beam, it's so much more vivid in person.
I don't have a host so I just have it hooked to my flashlight for now, I found a guy selling two "laser 301" lasers for cheap, one red and one green so I think I'm going to swap this module into the red one, they're only 100mW tops. But they both come with a battery and charger so for $20 for everything and not having to wait on shipping, I don't think it's that bad of a deal. especially for something to learn on.
I think I'll have to upgrade my lenses, the one in this 250mW module seems a little wonky, like it's flopping around while you're focusing it.
