I purchased this in February after discovering that DISH Network was billing me five extra bucks a month because I didn't have a phone line connected to my DVR. The RC930 was a little less expensive back when I bought it than it is today, but it was well worth the cost. Now DISH doesn't bill me the five bucks and as a bonus I get caller ID info on my TV screen when someone calls. Hookup was straightforward and worked the first time. Highly recommended for caller ID-capable DVRs.
