Just to finish this thread.....I finally decided on the Janome 6600P!
Great machine with tons of features for the price. Plus, I felt this machine was very sturdily built, didn't feel flimsy at all. I test drove it last week and will pick up the one ordered for me this Thursday. Can't wait to play! I've already joined the Yahoo group for this line of Janomes.
Machines I had considered included: Pfaff Ambition 1.5, Viking Tribute (I still like this machine!) and Pfaff Grand Quilter.
