90 Monk: 3300
89 Warrior 3400
85 Warlock with full tier 3: 2900.
Considering my warlock should be worth so much more than that due to the tier 3, i wouldn't really take it serious.
But for characters made after the achievement system got in, it should work decently. though i would never pay 3300 for a char only because it got a few achievements that is easily obtainable.
