In addition to the Niles and Russound, I'm looking at the Elan Z Series for multi room distribution. Anybody have any thoughts? Ideally I want to piece it together and not spend too much at the outset. I'm also quite happy to programme the keypads myself but one dealer has told me that Elan won't allow that. I find this strange considering the wealth of info on the net regarding the programming of Niles/Russoud/Xantech systems.
