I've been looking at green lasers, especially at dealextreme.com, but that site seems to sell mostly lasers with no IR filters. From what I've read, an IR filter is a necessary safety feature.
I'm looking for a green laser, 5 mW or more, and with an IR filter to use for astronomy purposes. My budget is about $50 USD tops, so should I take the risk and buy a cheap, unfiltered laser from dealextreme, or is there somewhere else I should go?
Any help is greatly appreciated.
