Some great prices (even lower) than the one I posted previously. This combines both Dyson's Click Frenzy pricing along with eBays 10% discount for Plus members, so there's some very good discounts on the higher end Dyson vacs.
Good time to purchase a replacement battery if your runtime is no longer optimal: the DC44 battery is $72 delivered and the V10 battery is $125.10
Thanks OP, good timing on the battery discount
