It's as much of a workhorse as its Brother counterpart - the PC 6500. I've had both. The Amazing box and card are available, Babylock owns Amazing box now. I've used it for a Viking Rose.
I have the no longer sold Cardworks from Babylock. I use it with a Pfaff 2170. I prefer the BL digitizing to Pfaff/Viking.
I have a 12x12 hoop. I've used it once. My favorite is a 130x130 adjustable. Does 90% of my embroidery.
