Flayer Jungle was a good place to level in classic, due to lots of monsters that are very easy to kill, especially with a lance. It also happens to be a good place to MF, at least with my experiences.

Items for trade:
Windhorn, Eagleforce, Doomfather, Grandbringer, Harlequin Gaze, Vampirecrest, Gladiator's Valor, Arkaine's Bane, and Shaftstart

Looking for Stone of Manald rings. Also, I want Hearld of Arreat and Zakarum's Face.
