For my 1st cab, I chose to buy an x-arcade. By the time I was done with the project, the only thing thats x-arcade about my x-arcade is the wood, PCB, and wires.
However, if I hadn't choosen to get the x-arcade (and cut it up and put an overlay on it) for my CP, I wouldn't have learned so much. Having the device there in front of you and seeing how everything works is great. I like the xarcade pcb so much I'd say get one even if you gut it and move the guts to your own cp. That is what my brother did with a tank stick. It all works excellent.
