I currently have a Performance 5.0 and a Passport 2.0 (bought to take to classes) and love both of them. I've never experienced any problem with the Passport 2.0 and have only taken it to dealer for a yearly maintance/cleaning. My first Pfaff was a Select 3.0 and then I purchased an Ambition 1.0 both of which I loved. I traded the Ambition for my Performance 5.0 and gave the Select to my DIL's mother as her machine had quit working and I wasn't using it.
