I have a Viking Platinum - about 12 yrs old. I don't machine quilt - except for a few smaller things - so no help there. Otherwise it's a dream. Auto tension is the greatest thing since sliced bread. I sew other things besides quilts and it's a dream to work with. There have been a couple of recent threads here on the board as to methods of going about selecting machines. Sorry-head is a little fuzzy this AM with the beginnings/edges of a migraine so I'm no help with a search right now. Maybe someone else can help with that. Good luck in your search.
