OMG i love my Vikings. I have the Sapphire 875 and the Designer SE sewing/embroidery. I have had the first for about a year and till today when i sew i keep yelling at home for the kids and say "did i ever say how much i love my machine????" "yes mom many many times...lol"
Many many spoiling features that i didn't know they exist before. Speed control, auto sewing without pedal, needle up and down, stop at the end of a decorative stitch, pivot, quilting thick fabrics, throat space, bobbin sensor, auto threader, variety of stitches, etc...so many to list and i am still learning how to use it.
Nothing that i don't like about it. I am a happy customer, and most of all i love the customer service i get. This is major for me for such an investment.
I bought mine last year for $2000 but i know you can get them cheaper now.
Good luck
