I guess I'm all alone out here, but I have the Brother 1500 and love that. I've had real good luck with it. There is no problem with different threads, and I can easily control the speed. A really big plus is that a dealer is nearby to make any adjustment at a moments notice. One time when it had a problem with the bobbin hook I ran it to the dealer and he made the tiny adjustment on the spot without charge, and away I went. That was three years ago.
