Valid!
There are still a ton of amazing clean air uprights out there to choose from, Sebo definitely comes to mind. I've always enjoyed the Panasonic style uprights just a bit more, I guess it's all preferential.
There's something about the older style motors that I like better than the new higher speed single stage motors, they just have a more robust tone to me. That being said, I've been eyeballing some of Prolux's commercial uprights... The 8000 is sexy 
and they still use Ameteks motors so that has to count for something. We'll see how long the Twin Energy holds up and when it's time to retire the old lady, why not try something new and sleek?
