I splurged about 4 years ago and bought the Brother Duetta for Machine Embroidery...I thought I would never want their Quattro. I also came across a Pfaff CV 5.0...and I was told that this was "the machine"...
I would buy another Duetta, never buy another Pfaff and probably not buy a Quattro. I don't use all the features, but they are nice to have...if you use them.
I mainly piece, quilt and machine embroider. I don't do zippers, hems nor special stitches. Wish they could do a machine for that!
