Hey Jmorris,
I actually have the mackie control universal (with 2 extenders and a C4 unit as well) I have to say I LOVE IT! I hated the dayum mouse and now that I rarely have to use it I am much more at home when mixing. The MCU actually helps me in every aspect of the recording, which I didn't expect. It is alot easier to arm tracks, hit record-stop-undo-start over, and everything else. I am truly spoiled now with the MCU lol. I have a mackie 32x8 that I use for additional pre-amps goin in, but I would never want to go back through it for mixing, the MCU has WAY more features. It is motorized, and has every quick access button you could ever need. I also loved the fact it came with the lexar overlays for whichever program you run. Also it is not much more than getting an additional break-out box to send channels back to your board. They are only like $999 from most anywhere. I have 2 of the extenders so I can actually have 24 faders in front of me, but the bank-up/bank-down buttons are alot less hassle then I thought they would be. Because the mackie control has the track names at the top of each channel you can see very quickly where your at. I would recommend it for you, I think you would have alot more fun and solve alot more problems/issues with that than you would bye going back to the board. Not to mention all the little problems that will most likely arise from adding another break-out box to your computer/set-up. Hope this helps!
