I am partial to Fluke's tele-data testers I use an OmniScanner2 on almost a daily basis and love it, for a basic residential tester that can test twisted-pair and coax you could look at the MicroScanner Pro. I see the kit with the coax adapter in the milestek catalog for $539. http://www.flukenetworks.com/us/Cabling/Residential+and+Basic+Testing/MicroScanner+Pro/Overview.htm
