What kind of budget?
Epic and Sebilite Croaking Dirk (in terms of a tradeable offhand) are still excellent until you get to the Velious uber mobs.
Bloodpoints, Bone Razors, and Trakasaur's Tooth are 1k or less.
Kelorek`Dar Spine Razor will probably be super cheap when they start dropping if not given away or sold to vendors.
