I have had the Janome 8900 for almost 2 years now and love it. It will do anything I ask of it, but does struggle with really thick layers. My recommendation (a friend suggested this to me when I was looking for a new machine) would be to take several 2" squaresof fabric, squares of your favorite batting and sit down at each machine and make a block with the 2" squares. Fold them in half over the batting and sew around the edges. Straight line or FMQ quilt the sandwich. This way you will find out how difficult or easy changing the feet will be. The dealer should be more than happy to help you with this process, otherwise, you don't want to deal with them. Just make sure you don't go when they are having a sale and are too busy.
