HouseDragon,
I love the Sapphire 875!! I bought it when they first came out and its lots of machine and worth every penny.
I like my vintage machines too. My current favorite is a Pfaff model 60 industrial treadle. I have a Pfaff 1222E set up in the Horn cabinet that she shares with the other machines that fit in this cabinet too. A quilter can't have too many "power tools"!
