I've been thinking that I want an X Wire wireless unit. Really nice stuff from what I've heard. But we all know that electronics tend to break over a period of time. And with the fact that these X Wires have been out for several years there is a good chance that issues might come up. Has anyone ever had to have theirs serviced? Is there anyone that is set up to service these and are replacement parts available? I would tend to think that maybe the current stuff may be the way to go just for the support. What do you think?
