Well let me know if you have any questions. I got mine last month and have played with it a little bit. I'm still waiting on my tank arriving so I have not fully set it up just yet. All of the control settings is GUI based so there is no programming you to do. If you have a good idea on what you want a controller to do for you (i.e. what you want to control), you can post a thread here on RC:

Matthias Gross (from GHL)
AQD_Ottawa (Michael, the N.America importer)
Stoneyscoral (Todd Cherry from CherryCorals)

These guys are quick to respond if you have any questions. Plus they will tell you exactly what you would need as well.

As for accessories and prices:

hope that helps!

-once I get my tank running, I am going to document exactly how I program the controller (with screen shots and photos) so others can get a good first hand perspective.
