Zom's Crazkling Bulwark, I picked up in Naxxramas off of some trash mobs. Nax is one of those raids that's so freaking long, most people just blow straight to the bosses. But you might miss out some decent BOE drops. The Tainted Waveling I picked up from Hydross the Unstable in Serpentshrine Cavern. Again, enchants consistently sell.
