Thanks for the suggestions, everyone!
We're leaning toward the Brother cs6000i right now. Of course, nowhere local has them in stock, so I'll have to have it shipped. Over a weekend. A holiday weekend. That's ok, I'm just excited.
The smart side of me says to go for the singer 401, but I'm almost positive (from the pictures) that's the kind my grandfather has and he told me I could have it the next time we go up there (it's in a table.) No telling when that will be, but I kind of want to get something 'new' this time.
