What is the worst component in your system? For me it was a URC MX-900 Genesis remote that a friend gave me for free. I quickly found out that in order to use it I would have to download the MX-900 editor software. Although this looks pretty straightforward, in actuality the software is not available on lie unless you are a professional installer or bough the remote from a dealer who is still in business. Even though the remote was free I threw it out because I didn't need another paperweight.
