for me, it was a few things:
Mobolazer 1 watt argons, inside local night clubs,
a 5mw red hene I saw ,I don't remember where,
and MWK lasers, where I went and saw high powered multi-line white light lasers at their open house, with tunable prism....
since then, its been draining on my bank acct....
still don't regret it though, as there is nothing that comes close to laser light, even side by side with moving heads or LED walls,,, way different effect!
