I don't believe many of us have any idea what would work when just searching around on [Ebay Link Removed] You're probably not going to see anyone posting up their Hoke or Parker. I think my favorite not so common valve is the Swagelok 'S' series. It's kinda like a smaller version of the Ideal valve.

I don't think I've ever seen anybody else using this one: (my personal reg)
