Touché!
I guess I had that coming... Dangit! Can't hear melectric car rev at the light!!! 
Honestly, I'm just starting to get "up'n comin" & "haz-bin" acts. They will accept my Mackie Thumps for monitors, as long as I have a sub for the drum fill, but that board is something they won't move on. It's funny, because everyone who uses the PreSonus for a little bit is impressed: because it is 1)super easy to learn, 2)very functional, and 3)sounds great. I have heard that the faders on the PreSonus are not reliable. I haven't had an issue yet, but at their price, they're still worth it. I'm still a weekend warrior. We'll see how reliable they are when I'm running them 2-3 times per week.
Don't get me wrong, I have nothing against the Presonus, and I have actually gotten to the point where I would rather see that in a small club/listening room than the typical GL2400 and assorted outboard. I think it is a great piece of equipment in its price notch. Its use in the proper place is no problem. I would not be surprised to see it at more and more big shows as a quick throw up for the opening act when the headliner is touring their own FOH (Venice seems popular for that now).
I just have a hard time believing anything in that price range will ever be rider acceptable for any act with the clout to insist item by item on the rider. The price of any top line technology tends to remain fairly constant over time, while the capabilities of the technology changes.
For the type of acts you are seeing I believe in crossrenting. If they insist on a particular piece of equipment I will be happy to go get it at a line item cost. That is always a good indication of how closely they are going to adhere to the rider. If it is negotiated in advance, there is often a lot of compromise possible.
