I think we all need to remember that some of these really super awesome/precise valves cost some serious coin if you're not buying them in an auction or new old stock liquidation type situation. I'm under the assumption that the OP has done some serious research and spent countless hours looking for these things.

With that said, you really have to view this thread as tool to help you identify a valve and how well it's going to work for you. A great example of this is the Parker HR3. It's friggin awesome and I never would have figured it out for myself. It's only because Bettatail and others have spent some serious time on this.

If you're really interested in finding these valves for yourself, learn the part numbers and what they mean and preform searches every day on that one auction site. That's realistically what it takes.
