Get ahold of a certified Panasonic dealer and take a look at the TDA system. Start with a 100 and everything but the empty cabinet will grow with you into the TDA 600. The system has a proprietary 'mini-cell' system that will work perfectly in your warehouse. Of course, a lot of other brands have pretty much the same features. As you observed in your postings, most problems wind up being dealer non-support, which is not a brand specific problem. To plagarize the real estate industry,'dealer, dealer, dealer.
