I am not a great sewer but would like to get into the craft. I just purchased a used Husqvarna Viking 6020 off of Craig's list. It seems to run beautifully but I was wondering, as it came with no accessories, if there are some I should look for. Also, does anyone know the differences between the 5010, 6020, 6030, and 6040 models? I see parts on eBay and am not sure if all 6000 series models take the same accessories.
