I have Brother Disney 4000D and don't use PED at all - unless you want to learn digitizing yourself, I learned the basics with Janome Digitizer and Generations previously so haven't found the need for PED - I have designs from all other sites mentioned above, including OESD, Stitch Delight (a favourite) siCK and a few more - when browsing sale items there is often a free sample at the end of a digitizer's page; just spend a little time browsing and you will be pleasantly surprised. Some other 'free sites' ask you to sign up before accessing their freebies so it depends on how many sites you wish to belong to!!!
