do they both have the different kinds of feet that you would be interested in?
are any additional parts comparable in price? can the dealers supply them for you?
how long does it take to get parts? i ask this because on the viking, the dealer i use says he gets the parts from europe and they take forever to get here.
i don't believe the first part, but i do believe the second part. (i only needed a foot pedal. i burned out the first one and the viking has a special one, of course)
do they both have differential feed? test drive them a lot and see what feels good.
