Once you have decided what you want (I prefer the recent basic Toshiba Satellite and Satellite Pro models myself), buy the thing from e-store.com.au they are the cheapest I can find.
I recently tried to get a cheaper price off 20 x Toshiba Satellite Pro 6100 laptops from them (usual price $4050.15) and the price only dropped $30 each so I think they are working on slim margins, so you are getting a good deal price wise. Judging from their help with the enquiry their customer service has improved substantialy as it used to be awful.
