The 4110 is on the CD I have and it was only about $70 from the dealer (you may already know that price). I have found it to be worth the price, as several things have saved me from making trips to the dealer, and on one occasion was able to trace a problem in the electrical wires that would have been costly if taken to the dealer (that was this past weekend).
So I figure it has more than paid for itself.
There are 698 pages in the CD just for the 4110 and the 4115 tractors.
Sorry, don't have one for sale (but might when I trade the 4300 in, whenever).
