Exchange Steering Rack

Hi guys after 520,000 km's the poor old steering rack in my wife's 96 Outback is in a pretty sad state and needs to be replaced. In the past I have used A1 drive shafts and Sbaru spares and will give the a call tomorrow to see what I am up for. Does any one have a suggestion for a place to buy an exchange rack in Melbourne. I am really chasing the cheapest item as I am loathed to spend any money on a car that is worth $75 with a full tank of petrol :lol:
