Droped to me last night, but I'm not an lv10 blacksmith, and, even if I was I wouldnt craft it.
Last night I made a search on RMAH and found none. So, if you buy, you can try sell there and get a bunch of $.
You may ask why I'm not selling in there. Answer: I don't see me spending money to sell this item there. I've spent money to get the game, I'm not spending to get more gear. I'll just try to farm them while playing.
