I just checked my inbox and saw your reply to one of my other comments. I was not aware that they were running such a good sale on the 21814, as it was over your budget when I typed the response you read. The 800 Series 21814 comes with a far more complete attachment package than the 400 Series with additions such as the CrossOver head with the built-in hard floor tool, the included miniature power nozzle, an angled fan dusting brush, and so forth. Also, the attachments all store on-board unlike with the 400 Series. One major difference between the 200/400 Series and the 800 Series is that the 800 Series has an extra two feet of hose, which makes a big difference. Between the 800 Series 21814 and the 400 Series, I would go with the 800 Series, because if you add all the extra attachments to match the set of the 800 Series, you will come to a close price to it and still lack the extra hose length, on-board attachment storage, dirt sensor, CrossOver head, headlight on the wand, and more. It is also currently a better deal than the 700 Series 81714 and the 800 Series BC7005 (the same as the 21814 other than the color) in my honest opinion.
