I must admit, I was very skeptical... $4.99 for a 74 page service manual. I've seen some very poorly scanned manuals on the Internet, but this one is VERY good quality! Even when zooming into 500%. Great Deal!
Incredibly clear!!!! Well done, complete and wonderful. It could not better than this!!!!
