think of it this way...
SOLID STATE WILL ALWAYS BE AROUND
Big gas lasers are a dying breed. Get one while you can.
ALSO... they aren't that expensive to run.
One kilowatt hour where I live is about 8 cents. That means I can run a small 120V argon at 10A for an entire hour and it costs $0.08
So, lets say a lexel 88 is 5 Kilowatts, but on house power it will probably be less. You can run it for an hour and it will cost a whole $0.40. Ten hours for less than 5 bucks...
Yeah they take a lot of power to run, but people dont realize it's not high power items that kill your bill, its all the lower power stuff that runs constantly 24/7
