Personally I never buy major components of any type of audio or electrical goods online unless it is a seriously stupid saving. Buying local allows for a much quicker, easier, pain and postage free warranty claim if anything goes wrong. Add to that you also have the expertise of your local audio shop to fall back on when and if you have any problems with any part of your system.
Go to Westside Sound & Image in Cannington and ask to speak to Fabian. Tell him Craig sent you, he'll sort you out with a good price
