There may be a few lurkers but the overwelming majority of folks here have CO2 laser machines, mostly cheap Chinese models meant to cut plastic and wood. I wouldn't expect a huge response....
If it were me I'd go to a trade show and check it out. IMTS is this fall, I'm sure there are others with the type of machines you'd be looking at. That would give you the chance to see several different machines in person and side by side so to speak.
