I'd say be careful with vanilla. I got one off eBay that was advertised as copper, but it turned out to have copper plated steel contacts.
I got a cartel from eBay that really is copper, with copper contacts. It's heavy, too, with a thick tube and excellent threads. Infinite is supposed to make a great cartel clone, with silver plated brass contacts.
