Need help finding a green laser w/IR filter

[oaaoaao]

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.

DX now have some Romisen lasers in stock.
These (or at least my L-D030 - SKU 12274) has an IR filter, though this seems to be a coating on the lens that is as hard to photograph as it is easy to scratch.

Better than I expected for £10 delivered though.
