Well I went and did it. I got a really great deal with the trade in of my 11000SE. I never used the 11000 because it didn't have Acufeed so it was just sitting there. I used my 7700 for most of my stitching. I'd like to keep the 7700 for just in case but plan to make the 15000 my primary machine. It is longer than the 7700 and doesn't fit in my large cabinet, so I had to get a chair that goes a little higher since the machine won't be sitting flush with the cabinet anymore. Plus I got the 48 months interest free financing.
