Okay.
NOVA, Optotronics and LaserGlow are all the best. You will get the best products and the best customer service from those companies
Dragon is also a good company, though it isn't as tried and true as NOVA and the others.
DealExtreme is a reliable place to buy cheap, crappy lasers. That may sound weird, but lots of us have bought from DX and they have good service. However, their lasers are technically 'scam' lasers, as they are of low quality. However, DX have a good RMA (returns) service and some people just keep returning them until they are good.
A cheap laser from DX is high recommended for people starting off in the hobby, just because they are so cheap

If you don't like it, you haven't wasted much
Wicked is great for accessories, lots of people have goggles from Wicked. However, their actual lasers aren't very good. They look nice, but are overprice and sometimes underpowered. Don't buy from them
If you have any more questions, you've come to the right place
