Keep an eye on woot.com. They periodically have refurbished Dyson vacs on sale at good prices. IMHO the new prices are outrageous. I've purchased two from Woot, a V6 for home and motorhome and a standard size upright. The only thing I don't like about the V6 is that it exhausts through the top and, depending on how you hold it, will blow on you. I'm surprised that Dyson designed it this way.
A nice thing about Woot is their shipping price. They're owned by Amazon so Amazon Prime members get free shipping, otherwise it's a flat rate of $5.
