Best place (vendor) for training material on PLCs

Hello everyone. I am a soon to be downsized(rightsized?)employee of a large multinational tool company. I am trained as a machinist, but for the past 8 years or so I have been also doing machine design and building, also including the PLC and CNC programming. I also managed to set up a basic SCADA system to monitor real time production status from each machine. Mostly simple stuff.
I am almost entirely self taught so I am constantly looking for new info. on this site and others. Now that I am moving on to newer(greener?)fields, I would like to know if there are any good programs out there where one can get more experience with these devices? I enjoy this line of work more than just "making chips". Short of going back for a degree in EE, what types of thing are out there? Any and all comments welcome.

THIS SITE ROCKS!

duh! check out the link at the top of the page that says, in flashing letters....
