Brother manuals are FREE and can be found on the Brother website. 

Some Ebay Sellers are selling you these same PDF files which they have downloaded.

BUT THERE IS A BIG PROBLEM WITH THESE MANUALS.

• The pages are crooked and are often at right-angles.
• The pages are dim or much too dark & the pictures are dreadful.
• Often you will find the pages have the bottom paragraphs chopped off.
• The manuals are often over 100 pages and it takes forever trying to edit them straight so you can use them.

WHICH EBAY SELLERS TO BUY FROM:

• It is better to buy your manuals from someone who has permission from Brother to sell them as this prevents
• A sudden disqualification from Ebay & your seller disappears for good
• No machine knitting support
• No refund if the CD is no good
• Rotten copies.
• While the older manuals (500 series) are bad copies, at least you know the seller has tried their best to edit them.
• The seller is likely to be a machine knitter who can lend you some support.
• Machine knitters love their craft & love to help others - resellers just making a buck or two don't give a cat's whisker.

LAST BUT NOT LEAST - THE PRICE IS GENERALLY THE SAME WHOEVER YOU BUY FROM. 

THE CD'S CONTAIN PDF FILES. THE SELLERS SELL THESE SAME PDF FILES.

THE VERIFIED BROTHER SELLERS WILL SELL YOU A GOOD COPY OR AS GOOD AS IT GETS.

THE UNVERIFIED SELLER IS LIKELY TO SELL YOU A DUFF COPY.
