Stick with ball baron. Seriously, you won't find anyone who provides better customer service, nor someone who knows more about just about any sort of round metal objects. And his standard for what is acceptable for him to sell is REALLY high. Before the ninjas, he didn't have anything like that in stock for a while because his suppliers couldn't meet his standards. That's the kind of guy you want to buy from in my opinion.

He sells ultra-shiny carbon steel balls too (pretty much required for most newer games since carbon steel doesn't retain magnetism very much). Last I saw, he was targeting July 4th to have them back in-stock. And his prices for those are the best you'll find on top of it all.
