I had a Viking for 11 years. When I wanted to upgrade, I went to the dealer.
After trying the 875Q, I asked to see the Janome 7700. She bad-mouthed Janome to try to sell me on a Viking.
Several weeks later, I asked to see a Babylock. She badmouthed the Viking to try to sell me on a Babylock.
I ended up buying two machines - a Janome and a Babylock - because I didn't really like the feel of the new Vikings. But not from her.
But that's ME. Forget what the dealers say and try out the machines. Trust your own instincts.
