I just purchased the Panasonic canister from AMAZON.COM for two hundred and thirty two dollars that's including tax and shipping! It should be here by the 21st and I'll be posting pictures then. I'm so excited!
Congratulations, I'm sure you'll love it. I recommend getting the Kenmore Hepa Q bags or a generic manufacturers Hepa bags for the unit. Additionally you can use a Kenmore PowerMate Jr. on it! This machine will also fit most other manufacturers friction grip slide on attachments.
I love HEPA bags! I use them in my Windtunnel and will also use them in the new Panasonic. I don't really have the need for a powermate Jr since we have leather furniture and no carpet, but it is nice to know one will fit if I ever do need it.
