I love these, I had a V6 (got from woot) and got a V7 and gave the V6 to my daughter. I was looking at the V7 on woot and a commenter said look at Dyson direct. Sure enough they had it for $2.0 more and when you buy from Dyson direct they throw in a tool kit that includes a hose. Hose makes it much easier to vacuum your car etc.
I checked today and they have the V8 for $200
V8 is out of stock
