Well, if you feel like converting 1st and 2nd edition stuff to your precious 3rd edition
, you may want to pick up the Menzoberranzan(spelling) boxed set and the D1-2 and Q1 modules.
I am old editions only...never caught on to 3rd edition. Guess that is the age coming out in me. Ruins of Undermountain boxed set is good, too.
