Just my 2cents worth but...
I have had my Dyson DC04 !!!! for years and years. I LOVE it. We have bad allergies and this Dyson still picks up everything known to man and then some.
When we build the new house I think I will have 2, one upstairs and one downstairs (well we can all dream can't we?), so I don't have to drag it up and down the stairs.
I love the Dyson, it's fantastic...wouldn't get anything else.
