Oooohhhh boy. I've done it now. Sold a bit of music equipment that I did not need, made the mistake of looking on Ebay, and bought a second Zendrum before I even received my first. Not exactly sure if the person is a dealer but he had a couple of new2012 ZX Z4 series listed and I bought one today. That will give me a chance to see which layout I like better, the ZX or the EXP. Now I have double the anticipation.
