I have played with or installed units from Compaq, Imerge, Entre, Escient and ReQuest. As far as I'm concerned, the Audio ReQuest is the only one that isn't a science project. You plug it in, it works. World class support, backup options, networking options that actually work and seamless integration with Elan Via panels and Crestron. But, like all the best things, it is more expensive than the competition. The new Terabyte model (thats 1000 Meg) is 25k.
