Read through the forums here, there are differing opinions on doing it yourself or going through a broker, and in the end it's a personal choice depending on how much time you have at your disposal - brokers are experts but there are stories of people getting a better deal themselves.... There is nothing to stop you making a couple of appointments with the main banks and seeing how you get on. If a broker can get you a better deal you can always choose to go through a broker later on.
