I don't know about black, but see if you can get red, its the next best thing next to purple. You can get 4oz purple Fiebings off of ebay for $4.50 + $2.50 shipping. I imagine black would be good because it can't be any different then Griffin, they are both pretty much the same product. You already know its going to stain, just because its a different color isn't going to mean its complete shite, but purple will just stain better.. I would go for it.
