I have recently purchased all three of Mr. Melore's books and feel that I have made a great investment. As I had no working knowledge of PLCs I would not have considered getting the lab manual without also getting [FONT=Arial, Helvetica, sans-serif][SIZE=+1]Your Personal PLC Tutor...A Guide to Understanding PLCs
[/SIZE][/FONT]and for just a few dollars more I was able to get the complete set.
You asked for opinions, and for what it is worth, this is mine.
