Hi, Does anyone use one of these? I have a great Viking machine but it is so heavy to haul to retreats etc. plus I worry about bouncing around the electronics and computerized parts. I see some great reviews on this little machine & it looks like it sells for about $150+/- which is amazing considering it even includes a walking foot! Guess it's a step up from purely mechanical and has some electronic components. If not this one, any other ideas? Just want something a lot lighter that I can count on. Thanks so much!
