I am, also, very interested in the Quest Plus, although I have not seen it. There are discussions at Pattern Review in the Message Board, plus reviews about the Janome and the Quest. I like the idea of the built in dual feed with several snap-on feet that can be used with it, the front load bobbin (rotary hook?) and the larger harp space. It comes with some extras, 1/4 in. foot, another plate, the table, etc., that are an extra cost with other machines. Let us know how you like it.
