I have the Brother 1034D..it was a fair price (a bit more than 200 ...) I bought it from Amazon....I was,t sure if and how to use it but the videos that came with it were good and I really start using it more and more and today I just can,t live without it....... I don,t use all the features it has ...and yes, it does have the differential feet.....I really made plenty of things with it....like decorative pillows and more....If I ever buy a new one it will be one that threads itself..but only because I am getting older and my eyes are fading....
