Hi Barry,
In my case it was not so much a purchase I wanted to do, but borne out of necessity. My old control surface developed three bad faders over the course of 10 days. I tried cleaning them, but to no avail. Since the old unit was almost 5 years old, I decided instead of repairing it, (it is no longer supported by the manufacturer) to replace it with something new.
I did test other equipment, and the Euphonix does the trick, especially for the price point. I compared it to other controllers many times it's price, and found the Euphonix held it's own against them, including the Digidesign Icon.
The only issue as far as setting it up, is installing the latest software for them first, then shutting down the computer, hooking up all the units, THEN turning on the internet router, then the controllers, then the computer. In my case I made the mistake of thinking they are plug n play, which for the first time setup, is not the case.
Once it is set up the first time, it seems to be able to go without a hitch. Today it works all the time very well, I can even turn the units off and on at any time, and the computer can keep track of this automatically. It even keeps working during a session if one unit gets turned off accidentally, which is great!!! Pro Tools did not freak out when my 2 1/2 yr old son turned one off while a song was in playback. He had a nice surprise when he turned the unit back on, as the faders snap to the bottom, and quickly too... it was fun to watch him react.
Cheers
