PLC Audiovisual Materials

I am teaching a training course in the fundamentals and basic applications of A-B Micrologix PLC's. I purchased DVD's from TPC Training Systems for audiovisual supplement material. They are outdated and not very good. Does anyone know of any supplemental audiovisual material that covers the basics of PLCs, for a fair price, that I could use in teaching the course?
