I am in the process of building my first dedicated home theater. My components will be located 40-50' from my RPTV. I need to run a composite and S-video cable that distance. I get a very good price (dealer cost) on Monster Cable products. Should I go with the M500 series or move up to the M1000 series? Although I get a great price the M1000 series is still double the M500's.
