What kind of dope are we talking about?
Its really a waste to buy them for the prices people ask on BH. Just keep at it. I've done it multiple times on F2P twinks. Can't say I've had to farm for more then 3 or 4 days.
Check the Horde AH for them. Nettiebay had a pair up for sale last time I checked. He also has hundreds of other twink items he posts on the Horde AH daily.
