DH is the best. I also bought my ZX off of eBay back in 1999, and DH helped me a couple of times over the year. It's really freaky to have the CEO call you from his cell phone while he's stuck in Atlanta traffic. In turn, I have helped at least 5 people (that I know of) buy new Zens directly from DH, and have at Zendrums request, demo'd my ZX off to several prospective buyers in my area. I also beta tested the 'Brick' for Zendrum and have the first 'Brick' ever sold. Performing with your Zendrum is priceless advertisment for the Zendrum.
