I purchased a Paff machine with an embroidery attachment appx 12 years ago. Paid way too much for it. Made the mistake of purchasing it from a dealer 50 miles away, so the classes were not convenient. I attended 1 class. I made a few embroidery squares but found it to be quite a challenge and confusing. About 5 years ago my sister bought the Brother 270D and let me use it for a few weeks(3 yrs ago). It was so much easier to use. We both now have the Brother 350, which is similar to the 400, but does not have the USB. My sister assisted/trained me with my machine for embroidery and the computer issues for designs. I found the sewing easy, but the computer downloading of designs and transfering to the cards was my greatest challenge. I still have to call her when I forget a step on the computer. We found the problem with my Pfaff was that the programs were out dated and no longer available for the newer computers.
