I work with
Rosco here in Australia. I have never used the
I-Cue, however have seen them done in demo's and have sold a few to local clients.
They are great if you have a low or non existant budget, a few profiles and wanna add some pazazz to your rig. The clients I sold them to used them in a club just for something different and yes, it is possible to use them with colour scrollers.
They are definatly a cheap alternative for moving lights, if your budget and venue support them, then they would be a great investment.
If you want anymore info,
PM or Email me and I can send you the fact shets I have and whatever else...
Hope that helps!
