So here is my board. It measures roughly 17" x 30". It has a flip up top surface that allows all my power cords and such to be housed underneath. My MXR talkbox is also underneath (my goal was to also have a Digitech Drop and Freqout, however I did not like how those pedals integrated and also new the Poly stuff was coming down the road at some point). The side panel has 2 female power outlets, 2 usb powered outlets and a male power outlet that powers the whole board.
This setup is great. When I do my solo acoustic shows, I bring the board, a powered speakers, stands and guitar. My monitor speaker and tablet plug right into one of the outlets on my board. My lights/main speaker plug into a 3 way extension cord which also plugs into the 2nd outlet on my board and I run a 25ft IEC cable to power my board to the wall. My full band shows I only have the tablet and monitor to run on it. It also has a bracket next to the power plate that I can put a mic stand into.
All of this was customizeable and I think I paid around $300-$400? I'd have to dig for that, and also to find the website. I'd gladly do that if you think you'd wanna check them out.
