I have been looking for a good deal on a Sapphire 875 and recently found out about the Tribute 140C. Has anyone done a comparison of the two? I have a Viking Platinum Plus that I really like a lot, but wanted a separate machine for quilting. I have very many feet, so would like to go with a machine that will use the same feet as the Platinum Plus and I think that the Sapphire does. What do you guys think? Thanks.
