I have the H.Viking Saphire 830 with the 10 inch throat. I love having the extra room for quilting, makes a big difference when shoving a quilt thru.
It has needle down,threader, and best of all a stay stich for beginning and ending stiching. It was 1100 when I bought it but has come down in price since.
It has one problem, you need to get the edging foot instead of the 1/4 inch foot because of the wide feed dogs. It is computerized.
