Recommended 5W+ 445nm laser?

Hello everyone!

I'm thinking of buying a Sanwu Silver 5W 445nm laser; however, before I pull the trigger, I was wondering if I may be overlooking any better options? In particular, I would prefer a 7W+ laser, but only if the host is relatively small (no larger than the Silver, so this rules out the Spiker). Another feature I prefer is waterproof. I don't mind if the laser is a custom build or commercially available.

Any suggestions?

Thanks in advance for feedback and suggestions!
