I have had a Pfaff since the early '90s. and love it. Yesterday, it wouldn't start so I took it to a Pfaff dealer who told me it just needed servicing and NOT to trade it in since it will go forever. While I was there, I quickly checked out the newer Pfaffs. I have my eye on the Ambition 1.5 but will wait for a while. Check out the Pfaff website. They do a great job of listing all the features of each model and have a comparison chart for various models. Decide what you want in a machine and then find the one that meets most of those wants. Enjoy the process.
