Well, as long as it does what you need, no problem. And if Elation recommended it, then I won't argue. They know their stuff better than I do. I'm just an end user! That's why there's so many options out there, trying to address various niches.
My main concern is that systes like that don't grow very well. You've also got fixtures that ideally shouldn't be placed on a dimmer/power pack as well. I always try to see out 3-5 years and see if the gear is something that will really be useful to me down the road instead of stop-gap solutions.
