I am close to buying an HDTV RPTV-CRT between 55"and 65".I have Dish Network at this time but I will have Time-Warner cable avail. soon and of course,Direct TV avail.now.I even have an old C-Band setup that with a little repair and a 4DTV sidecar can become operational.My question is this:Should I buy a set with the built in tuner or should I just get a unit from my service provider?Are there any advantages/disadvantages either way?Thanks for any help you can offer-I am in brain overload over all this! :user: HAl26
