Are you looking for handheld or desktop labby style?
The labbys can be found for around $860-900 from china.
Handheld ones are in the thousands of dollars, if you can find one at all that is actually 1W. Most ones that claim 1W are bogus and meter at like 300mw.
You didn't know how bright is the 1W green.
I have for sale one green 400mW, its 2 times brighter than my 2W 445nm laser. Burn things really quick. Let me know.
