with the AE - the big expensive bundle is the auto mechanics bundle including software for multiple manufacturers (the list is avail on their web site).
You can purchase the reader itself separately, or as a package with the Ford Advanced Bundle. (don't remember the pricing - but it's all on their web site.)
The updates are not required to continue using the software and reader you already have. They are only for software updates to include info for newer models that may not have existed at the time of your original purchase, and possible updates to the software itself.
Being on a budget, I'll buy the software for other manufacturers as the need arises. Happy with the purchase so far, and haven't had to spend anything extra to scan Fords built at or before my initial purchase.
