Sure. www.ebay.com/itm/162559817198. This is a 303 with key lock switch on the tail with a side switch to activate plus a battery and charger for $9.98. Took me 30 seconds to find this one. Try searching for 532nm laser pointers if you would like something different.
My point is for someone ( the OP ) who knows nothing about where to buy a green pointer..........that Sanwu has weeded out the weak ones, and on ebay you may buy a hunk of crapola, so for a novice buying a tested cheap pointer may not be the worst way to go.
Sanwu 18 dollars and tested or at least trustworthy.
I have gotten few duds when buying these on eBay and if I do, I always get my money refunded. So, it is up to the individual who is shelling out the money. Last time I got a low power 532nm pointer, it had a tailcap switch on it, not a key and no other switches anywhere. I think I paid around $8.00 for it, so not a great loss to me.
I "know" you 'know about the glasses'' but do you? only the very expensive will work for most 'color' lasers we see..some just for one color.
Buy your laser from a seller who sells the glasses and get both same time- or from a member who will add glasses/goggles and you will tell them its OK if they are not perfect new-- MOST members started with inexpensive eye protection but upgraded soon- and we have 'extras' then when you can buy new glasses you will have spares for a friend--REMEMBER-- unless you are alone.. the others around you are in danger should You get CARELESS.--
MANY GET INJURED trying to burn things.. we hope you 'grow' out of burning things-- there are ANY more enjoyable projects you can do with lasers.
