Dyson V6 Absolute: $299: Target Clearance
(PS: Brickseek listed that it was out of stock in my area but that wasn't the case in my situation)
Not too bad of a price if your in the market for the top of the line V6 model...
Check this video out where at the 2:15 mark, they start to compare the V8 with the V6 and it would appear the V8 is marginally better. The so called 40 minute runtime on the V8 is deceiving in that it's only 40 min for the small non powered tools. If you attach the main brush, the time is about the same as the V6.
