How much can you expect to pay for one to do a good job?
I bought a bagless upright for under 60 bucks and that included delivery to WA to my door. They have containers of them so if you're not in a hurry and live around NSW you could probably pick one up midweek for less then 40 bucks including the delivery. Works as good as a Dyson and is just as much a PITA to empty as a Dyson.
