Satellite radio is a high quality radio service that is static free, mostly commercial free and currently censorship-free. Special satellite receivers, costing around $50 are needed to pick up the signal. The two satellite radio companies, Sirius Radio and XM Satellite Radio offer competing services, both costing $12.95 per month. CNET offers the best comparison review of the two services. If you don’t care much for sports, reviewers say you should consider XM, which currently has the widest, most innovative variety of hardware. A good overview is Consumer Search’s review of satellite radio services and hardware.
