On costs, for anyone having the misfortune to be hit up by the Australian Government on customs duties (which way outstrip GST), it's not hard to work out where the money goes (unlike digital downloads). Customs Duties add big bucks to any overseas order worth more than a K.

The Autobrite Snow Foam lance/pre-wash is great fun, and works well. You still have to wipe to lift dirt, but it helps much.

Definitely recommend getting a pressure washer with the longest lance hose you can afford - makes life much easier!
