    That, and the fact that the cost is typically an order of magnitude (or more) less per mirror!

    You performed shows with a DIE-ONICs ? You have my utmost respect... (Laser Ionics, notorious for broken gas reservoirs when traveling, but highly cost effective in use!) Not easy to change the tube, as it was glassed in through a hole in the resonator base. If I'm wrong, that is the other blue Ion Laser, made in UTAH... A whatchamacallit... I can't remember, but much better made...

    DIE-ONICs. Cute, I hadn't heard that one. No, this Laser Ionics Model 554 mixed-gas laser was for a static planetarium installation. I agree entirely on what a pain in the ass it must have been to service it. Luckily, the planetarium client bought the laser, I designed and built the 4-color, 3W projector and graphics control system around it. I don't accurately recall, but I think the tube lasted 3-4 years of 11 shows per week use. I saw the projector a few years after that and it had a Spectra Physics 164 Krypton laser head on it.
