My first serious laser was a ALC60X and I loved it! Even with the squirrel cage blower it was still way too loud (living room show). That and it was hot. I was contemplating a lexel75 because they are water cooled. The problem is, they are water cooled. Hoses and running water or heat exchanger.... too much to deal with at the time. I would love to have one now! Even a 60X or an Omni532 would be fun to play with again, if only for the nastalgic value.
