I am not a fan of combo's. I did have a brother combo and didn't like taking the time to switch items back and forth just to do something simple. The 6600 is a workhorse, and has the thread cutter. You could buy two separate machines, and that is what I have done. While I'm sewing, my label is being embroidered at the same time. The Horizon 7700 is a wonderful machine, 11" throat, the 11000 is nice but again, as with most combo's, should something happen to one part, you can't use the other section.
