I was going to say have you ever looked at a dichroic color changer. They are not noisy like a color scroller and you NEVER have to replace a gel string again due to it using glass. The price isnt a whole lot more than a regular scroller but it pays off for it's self in maintenance/expendable savings. They sea changer is one that comes to mind. I jumped on the color changer wagon when Highend came out with their color merge.
