Tallchick - that was one thing I considered. I don't have a big house but was hoping to keep one of my "portable" machines upstairs and the other downstairs. (The White is in a cabinet, currently upstairs...where it will probably stay. It weighs at least 40 lb.) The 6500 would not be the easier one to move around, for certain. It does come with a rolling tote as part of a package from SewVacDirect. The Juki has its own hard case, which is always a plus. Unfortunately, neither machine is available for me to try. We have one Juki dealer 40 miles away. I'm not sure I want to deal with them; they were kind of pushy last year; for some reason the owner rubbed me the wrong way. My other half did not get quite the same impression. They sell the F600 but do not have one in the store, so I would have to order it. I finally talked myself out of seriously considering the more expensive 2000QVP - which they do have on hand. For $300 more, its features were not essential for me.
As for the 6500, the two local dealers both said they cannot get it for me as it's being phased out. It would have to be purchased online.
