I just rang Dyson and bought a new one. It was $100 or so, inc free shipping.  I bought a new rollerbrush thingy too at the same time.

 

Once both fitted it was like having a brand new vac again.

 

I really wanted a V8 Animal too, but this was way cheaper... Just got official route.

 

Our officially bought one actually died about 2 months after I bought it (orange light flashing, wouldn't charge) and they shipped me a replacement no questions asked.
