Help getting a green laser diode?

[itsmei]

Hi, i have looked around on the internet and i have been finding just green laser modules not diodes. I have made a red laser and now i want to make a green and i need to research first, i am a noob at green lasers. I was looking at this one:
Individual High Power Bin Green Laser Module V2 - Detailed item view - OdicForce Lasers Online Shop

What is a "Bin Green laser Module", what i mean to say is what is "Bin"?
I want the 120mw green laser for £38, is this a good price?
How many mA should i drive this diode, or will it come with the right amount of mA?
What battery would you recommend using for a 120mw?
If you know a better place of buying a green laser diode or module please say, i would prefer a green laser above 120mw.

:thanks:

Currently consumer green lasers are usually dpss laser systems. One company did create a green diode but that is still a few years off to the consumer.

Bin in this case might mean that They check the modules and put the best ones in a special bin, and the average ones go somewhere else. It's like cherry picking.

The module are case positive and usually take 3v-3.6v. current is preset on the driver

Ok, so i guess i could just use one of my CR2, 3.0v batteries on it.

Thanks
