I've only seen a
coemar fixture 2x. Once when I got to demo a 575
watt moving head about 4 years ago. Probably a prototype for the one you're using. It was terrible. But like I said, it was just a prototype.
The other was the colorcyc 1200, which has been replaced with a new model. The colorcyc is an outdoor color mixing
fixture and I thot it was well made. It was left in a downpour for 5 hours and didn't quit the whole time. Good color saturation, also.
As for the Minimac, it had one huge problem. The wiring harness was crap. Not the design of it, but the actual wires.
Martin replaced it with a new harness which they were willing to either
send to the owner or install at their service department. The new wiring harness makes the
fixture work 100% better and more reliably.
The
Mac 550 (comparable lamp to the
Coemar) has some software issues, but is still better
IMO due to it's feature set. The software has been updated, and it's fine now.
For something in the same price as the ispot, I'd go
Mac 250 Entour. Since the design is newer, it has improved optics over an older design 575
level lamp, meaning the end light output is better with a smaller lamp. Plus, it's lighting fast for a moving head. Still not as fast as a moving mirror, but really fast.
But in choosing, I'd look at the service behind the product, also. Regardless of how reliable a
fixture is, who is going to fix it when it does go down? How quickly and how completely are they going to fix it. If you are unsure of the service, stay away from the brand.
