Thanks guys! I've seen the Profilux in action at Progressive, and Garreth has invited me over to see his (he's got way too much setup on his

). But I'm leaning towards the Apex, it looks like it will do all that the Profilux does within the scope of my needs, and is way cheaper. Adding things on later looks cheaper too. I love the shiny blue lights of the Profilux, but not $500 worth -lol
My only hesitation is expandability, as a full scale fishroom might be in my future plans down the road, and I don't want to limit myself. Although, with the Apex, I'm not sure what it's limits are.
For those using the full Apex, what can it NOT do?
