I know how most of you don't recommend most amazon.com lasers. Are there any of them you recommend? Preferably around 30 mw. And how bright will the beam be at 30 mw?

30mW is rather bright if you havent seen it before, but then again if you buy it from amazon all you will have is an overpriced <5mW;)

EDIT: Wait, you all ready have a thread here on the SAME topic, why make another? Just buy the laser from rayfoss.com.
And seriously if you want 30mW vs 50mW to 'cause your eyes less damage' as you posted in your other thread, then maybee you should wait and buy a laser when you get older.

you can find 30mW rather cheap at O-like and rayfoss, but never buy at amazon, also 30mW is pretty bright for a 1st or 2nd laser, but it wouldn't hurt a fly, in the sense it produces no heat to burn.

Why do you insist on Amazon? The only two cheap lasers that are almost always up to spec here are the Rayfoss and the LEDshoppe pen. Check them both out.

If you read his other thread, he says something about his parents buying it for him, they probably dont want to buy from china.
@souljasai- I hope that you meant that 30mW would'nt literally harm a fly, which it would, just wouldnt kill it. 30mW can burn if the focus or divergence is good, and even with bad divergence it can and will cause serious eye damage and retinal burns;)
Even 5mW is bad for your eyes, just because it is low powered doesnt mean it wont hurt you.

I bought two 5mW greens from that etimeshop guy on Ebay that some LPF members have left positive remarks about. I do not have a LPM, but I am sure that these are over 5mW. They were like $7 or $8 shipped each, and probably are putting out 20mW or better of green. Divergence sucks just like all of them, they don't burn stuff, but they are bright and very inexpensive.

Yeah, I got a few egay pens that are well above 5mW, one of the greenies is 20mW on target with almost no see-sawing and nice divergence.
And I have recently bought a blu-ray 5mW pen, and according to the correction factor for 405nm on my LPM I its putting out near 100mW

I know what you mean, I'm just used to high powered greenies. I always buy lasers around 150mW or more

Yeah same here, It took me a while to accept my 473nm could hurt my eyes when ive been used to using lasers 200mW and above, it is very easy to forget that 'weak little 20mW' can actually cause such serious problems

technically they never lied or mis advertised, the lasers are marked and sold as <50mW or <30mW or <whatever mW. Well 5mW is less than all those, so they really are telling you the truth, infact I have an amazon pen rated <50mW and it says on the label that it is a class IIIa which is <5mW.

that is a sticker... I have 100's of those, that say various outputs, and some place in china they manufacture 5mW's and sell them to amazon, and china either mis advertises or amazon... I think it's amazon. That label is never true... I bought a 200mW, and gotten scamed before, it was really 5mW...

Not uncommon at all, even so with higher quality lasers, both my PGL's stickers say peakpower <than 500mW and a range of wavelengths(ex. 430-473nm)
But, it is not amazon selling the lasers, it is various people and online stores selling them through amazon, just like one would do on ebay, same concept but no auction. Amazon does sell some things, but alot of it is just stuff from different people being put for sale online, one seller on amazon even sells soda, and charges $28 to ship a $5 pack of soda...
So in short amazon quality control is pretty lousy IMO, but its the sellers that are lieing to both amazon and the consumers....
