Oops my mistake! I have a 2012 Sentria but that's actually a 2008 (I think?) Sentria I got from CL. Runs perfect but cosmetically it wasn't great until I did the paint job. The bag is painted, not dyed, and the paint doesn't affect the performance at all. It still runs like a champ and it looks awesome in use! I didn't paint the wheels because that material stays tacky after its painted, even with a fixative. So I just left them. I sold this black one to a friend. I'm currently doing the same thing on a Sanitaire SC-899 I also got on CL.
BTW, if anybody hasn't heard of it, list-alert.com is a great website. It watches Craigslist and sends you an email when your item becomes available.
