I started with the 7700, later upgraded to the 8900. It has a much larger foot pedal, seems to be even quieter than the 7700. The 7700 had an annoying metal stem that came down next to the left side of the needle. 8900 does not have this. Also has a 9mm wide stitch (makes a lovely serpentine stitch). For that price, I would see if the dealer will include the table--it is worth it--love the table.
