We got into embroidery 1 year ago and went with 6 single head machines. Was a lot more pricey, but I have to say when you get a day of multiple jobs of 12 - 36 pieces (which we see with embroidery more often), you can't beat the output. Although from here on out we will only be getting multi head machines.
We have Tajima, but wish everyday they were Barudan. Live and learn!!
