What cordless vacuum cleaner should I get?

[sufur]

I really need a new vacuum cleaner, I still have a corded one. I automatically started looking at Dyson as that's what I've always gone for, but are they really the best - I'm not sure? ...They're bloody expensive.

Shark lift away and dyson animal get raves.

I've got the Shark cordless one and it's brilliant, far better than my previous dyson.
