AB schematic blocks / wiring diagrams

I work for a traditionally MEP firm that uses Autocad MEP.

I am now doing controls and I am having a hard time finding good schematic blocks for AB I/O including ControlLogix cards, cables, and terminal blocks.

Am I missing some goldmine of freely available, quality blocks or do I need to buy 3rd party libraries or Autocad Electrical?

I would like to invest in Autocad Electrical sometime this year if I can keep the work coming in like I am so far. I would love to get those dynamic block libraries for schematics.

Thanks,
Mike
