I have been interested in this machine myself. Maybe I will start a secret savings. Can't do one in the immediate - but if I just start setting aside a set amount of money each month - I think it would eventually be possible! I tried one briefly in a local sewing machine store. Love all of the space, makes it much easier to maneuver a quilt.
There is a Yahoo forum called SewItsForSale (I think that is the name of it). All things sewing offered for sale (and people post what they are in search of as well).
