I am looking to buy a 405nm laser that does about 300-400 mW. I don't want to spend too much more than a hundred dollars on it, so I was looking at the Power Rock. However it doesn't have the safety features on it. I like the key switch and the remote interlock features, but a lot of lasers don't have them or are rather expensive. I would also prefer if it is focusable. Can anyone point me to some lasers with the safety features that are decently priced? I'll take lasers with no safety features as ideas as well, though I'd prefer they had them.
