introduction / new laser

Hi all im new here..
I just purchased my first green laser (after some research) from DX (i figured i'd be cheap dor the first one)
i cant post links yet but its sku 12340 "100mW Flashlight-Style Green Laser (18650 Battery Included) * EMS Express" $131

So anyway #1 is that an ok buy?
#2 anyone have one?
#3 im thinking of building a robotic mirrir assembly, or buying one.. where do i start?

I don't own one, but here's a review of the 150mW version: http://www.laserpointerforums.com/forums/YaBB.pl?num=1213699039

It's a good review, so I reckon you've made a pretty good purchase for your first laser

Robotic mirror assembly? Uh, okay, what do you mean? What do you want to do with it?

well i want to make cool effects like a mini version of what you would see at a rave.. they have little micro motors and you controll them with a laptop... Im a prety smart guy when it comes to electronics so i could build it if i knew where to start.. i would buy one if the price was right..

PS ***** thanks for the link... i guess i did make a good buy

Ok i got a question aboute this laser.. Can a rechargable battery be used? are lithium rechargable? do NiMH work OK?
