Angie: To buy or not to be buy is a personal choice. We take our decision & live by them. The TV programs are geared for selling airtime not to give advise. I have been on such a program & I know that their research is very basic & is no more than a local tourist or council website can provide to any Citizen.
An informed decision is a better one even if it goes wrong. Relaying on TV presenter to make you money is very naive. If this was the case why are they presenting on TV. They should be investing and counting the dosh that they have made for themselves.
