We have a Senseo at home and one at hubby's work. I don't drink coffee, so it just made sense to get a one cup at a time machine. We also save money by ordering refills on Amazon (subscribe to them to save an extra 15%). I'm not looking to buy or replace one, but this new Senseo rebate deal might be one that you are interested in as the holidays approach. Basically, you purchase their Black Senseo Machine (Item No. SL7810-65) for $70 and then send in for the $20 Prepaid card as the rebate. This offer ends 9/30 and you'll need to mail it in by 10/15. Senseos make awesome gifts (I've given them to my family!) and would definitely be good for a single person.
