Specialized Tools for Head Gasket Replacement

I need to replace the head gasket on my 1994 325ic with the M-50 engine. I need the set of specialized tools to do this properly. As I understand, the critical tools are:
- Camshaft holding jig
- Flywheel lock pin
- Timing chain tensioner

I hate to buy these new, as they are for the most part, one time use tools (hopefully).

Does anyone have a used set they would like to sell, or does anyone know where I can rent a set?

Great article.
I spoke with Tom at Pelican parts today. He had me send an e-mail to Wayne asking about the tools. Waiting to hear. I found a set of tools on e-bay for about $100. Has anyone used these? Are they good quality?
