I have the Brother 8500d.
If you want to use designs from the internet on your machine you can only use the embroidery card. You can buy these with designs or get a blank one with PE Design basic
You can get designs from the internet (www.emblibrary.com) and transfer them to your card. Only thing is you need the amazing box or PE design lite/basic so that you can write the PES design format from your computer to the card.
Remember you can only use designs that are designed for your largest hoop which is the 5x7inch
It is a great machine.
