Boo,
I'll tell you what I don't like about it, since you asked. Bear in mind, there is a lot I do like about it!
1. External power supply. I hate them.
2. No dedicated button for mic settings. Shouldn't be a problem for you, but I like to fiddle with them a lot. I like to be able to turn the Mic DSP off and on and use the Talk function on the Tyros.
3. It's really heavy, nearly 20 pounds!! After lifting all those bricks, can you handle that?
