i'm in the market for one of these machines too.
i've taken all 3 on a test drive and none of them totally shined over the others.
they're all very similar with very similar features.
i have a local janome and brother dealer so when its time to hand over the cash i'm just going to go with the person that gives me the best price and the most accessories.
i'm waiting until the heat of summer time when no one is sewing to make my purchase - this way they're good and primed to make a deal.
