Congratulations! Did you end up getting it from the Mt. Pocono Sew & Vac booth? I purchased an Accuquilt from them and they were selling their Janomes like they were ice cream on a hot day. if you did, I was really impressed with that business and would recommend people to go there.
Now, off to see what a janome 7700 is ...I have the basic janome- and I really like the quality. Had mine for 15 yrs and 1st time I had to have it serviced was last week (for an itty bitty problem).
