Couple things:
1. You should post a thread in the Welcome section to tell us a little about yourself!
2. You should read the Rules and Stickies as they will shed a large amount of light on many questions you may be tempted to simply make a thread for.
3. See number 2, seriously an important step for integrating into our community as most of the members here do not like to spoon feed you the information.
With that said, and pertaining to your post, I have a few questions for you and a comment.
1. Does Wavelength matter?(aka color)
2. Is your goal a burning laser or a laser with a highly visible beam or both?
3. Do you own safety glasses rated for the wavelength you will be getting? It IS necessary....as long as you like owning eyeballs.
Lastly, if you want quality, I would recommend Jetlasers. They produce very high quality lasers and have great customer service.
Other quality brands(forgive me if I forget a few):
1. CNI
2. Dragonlasers
3. Skylaser(LaserBtB) ....they seem to be well received here and seem to be up to spec consistently.
For 470 dollars you should be able to get a high quality 500mW laser(depending on the wavelength desired) and a pair of safety glasses.
Hope that helps! And again....Welcome section and Stickies, get on that
