I'd strongly suggest you look at the Selecon Aurora line of cyc lights. We currently have 20 (3 cell) at work, and I've spec'ed 20 more sky cycs and 12 ground cycs for our new space. They are for the most part really well made and thought out units. Great light output, very even field, and good color life. I'm very happy with them, and don't hesitate to recommend them at all.
My only real gripe about them is how the gel door is attached. On the 3 cell units they have a weakness--the door is too long and it flexes. When you do that you sometimes bend the hinge pine (that's 44" long). Once that's bent, the door does not work correctly anymore. I've spoken to their US rep, the guys that came over from New Zealand to LDI, and someone in the factory about the problem. I'm not sure if it has been resolved, but it's something to be aware of.
The next real advancment in cycs is coming from LED's. Every 18 months they get brighter which means in about 2 years they should be completly usable in any theatre situation. The ones I've played with held up decently against other lights but I think we're gonna keep seeing more and more LED cyc lights popping up on the market.
