I purchased a Bernina 350 almost 20 years ago and have used it almost to death. It only has a 4x4 size motif and uses the PES format. It is a machine made with a Brother patent. I just recently upgraded to a Brother PE780D. It has Disney designs built in and the good news is it also is the PES format so I can use my design cards from the Bernina in it as well as use a USB stick to import designs. Over the years I have purchased several thousand dollars worth of embrodiery cards, cds, a Magic Box etc. as well as thread, stabilizers etc. I can use almost all of it in the newer machine. I also paid almost half as much for the newer machine as I did my origanial, less than $1000. I have always prefered the stand alone embroidery machine because I can have it sewing out a motif while I am working on my regular machine or serger. It also has the 5x7 capacity which allows me to sew out a bigger design.
