There are prices listed on different sites for reference. The machine site shows the largest hoop for the machine at about 8x8. The embroidery field is always a little smaller than the hoop.
Ask for a machine demo with the dealer to see the features. Ask for thread and stabilizer pack to get started. They can add this to the deal for you to make the sale. You will also need the bobbins that fit the machine. Ask to see the actual stitch count on the machine.
Is there still a warranty on the machine? Do they offer no-cost classes so you can learn how to use the machine features?
What type of projects do you want to do on the machine? Is the sulky thread rayon? You will probably want polyester thread for the machine.
Check the size and compatibility for the usb connection. I only load a few of the designs on mine when using machine embroidery. If there are too many designs it takes longer to load. Good luck on your decision.
