best of show imo was the profilux controller.

currently in germany, there is only one in NA so far i think (canada). its biggest selling point (for me) over the competition is its inclusion of
wireless ethernet access along with both web and windows app interface. that is the main reason i have yet to buy a controller; anybody using a controller that uses a serial port is living in the stone age.
only downside personally is that it is focused on T5 lighting control (dimming, etc). guess thats b/c its from europe. it obviously can still control MH or any other lighting, so its just a downside for me b/c i dont run t5's!

one neat thing they showed me was the different weather modes (imagine one called "lightning storm", it was pretty cool)
also pretty sure it is tunze controllable, which i suppose means you wouldn't need a tunze single/multi controller if you had this. not sure about that tho.
it also has a seperate screen (extra $) which is display only and meant to be mounted in sight while viewing the tank. that way you can easily scan over your tank params without having to open your stand or anything.
another cool feature is the expansion card capability. so things like redox and conductivity cards/probes can be bought and added to the system later without having to buy an entire new unit.
heh, didn't mean to go on like this but i just cant find anything wrong with the profilux other than the fact that its not in america yet!
