I'm looking for some cheap (sub $20) lasers for that wont die for absolutely no reason, but if one does its not a big deal. Are the 301 pointers on ebay any good? Wanting red, green and blue and would like at least the green to be very easily visible at night.

Or is it just best to build my own pointer for something like this?

For sub $20 and green, the 532nm 301 style pointers are about as good as you can get - they're okay - mind you you get what you pay for and for $5-8 you understand that won't be much...

Stuff like this tends to be glued together so it makes it pretty impossible to muck around with it etc. A 301 532nm green (usually rate 50-80mW) should just about be bright enough to be beam visible on a dark night. Reds and Blues, you'll need quite a bit more power for the beam to be visible. If you want the dot to be visible instead then even 5mw would work :p
