I've had great luck with FL epic drops. Farm the place solo on my DK (in only quest gear). Last night was a great night in that I got 3 epic drops for only about 2.5 hours of farming. Got the tank trinket (Scales of Life?) and the strength/exp neck x 2. Sold the tank trinket pretty quickly for 35k and listed the neck for 30k, but would take 20-25 if someone asked. I'm still hoping for the polearm or xbow since they are huge sellers.
Edit: I have that SP dagger on my resto druid. It will last me until the rag hammer, but if I was a caster DPS, I wouldn't take it. There are way too many +hit weapons in Firelands especially when you could sell that thing for 40k+ and down a few bosses for a staff or other +hit caster weapon.
