Best of luck Curtis!
It looks like you landed yourself a fantastic canister with the Miele S8 canister partnered with SEB236 power nozzle. I wish you the best of luck with that machine.
Wishing you a formal welcome to the site with many more postings to come from you and a continued experience from your vacuum learning and feedback from different machines. The D4 model above has left a bad taste in my mouth but the many of the others you listed are quite powerful machines. I'm sure you will get much appreciation with your Miele along with gaining interest in Riccar, Simplicity, Royal, Aerus, Hoover and others!
Best of luck!
