Well, you just hit the nail on the head:
LOW COST FIXTURE.
It's going to be a while before prices drop enough for the LED technology to become cost-effective to out into low-cost fixtures.
Overall, I am pleased with my 64 LED Pros, but as I said, the can't keep up with a regular ParCan. But, I'm an audio guy, and seeing RGB mixing meant "screw gel sheets and larger set-ups", which they've done quite well with. But, as I am being pushed into more complex shows, I'm seeing strengths and weaknesses, forcing my knowledge of lighting to expand, whether I want it to or not, in order to remain a top player and performer in the market I am in.
The only down-side is, aside from the cost, MORE people need to have this hands-on type experience to learn this. There's no other way. Books can teach but you gotta see it to understand it. Then experience is knowledge, and that will stick forever.
