I took my Ambition 1.0 in for annual maintenance and cleaning in February and ended up looking at other machines (Performance 5 and the QE 4.2). I went home and searched for reviews and watched the videos posted on Youtube of both machines. The next weekend the store ran a special for us Seahawk fans with an additional 12% off of the sale price so went back and ended up buying the Performance 5. Am extremely happy with my purchase, watching the videos I think was the final deciding factor in which one I purchased. I traded in my Ambition 1.0 and kept my Select 3 for a backup as the presser feet are interchangeable between the two machines.
