I'll toss out The Hole as an option. Tons of vendor drops and plat from the mobs, especially for the level. You'll often find folks camping the very bottom temple area, but you can head up the tunnels to the city area and hunt the ghost type mobs there instead (which will still be good exp at level 65). I wouldn't get too fixated on specific zones for loot though, almost anything can be good. It's also worth noting that you really want to find mobs that are relatively low level (but still lt blue), that you can kill at a faster rate over higher level mobs. A 5-10 level difference in mob level rarely equates to more than 150-200% more loot/exp per kill, but often can result in 200-300% faster kill rate. Unless you're actually going for loot drops you can use yourself, you almost always going to be better off sticking to the lowest level mobs you can find (again that are still lt blue) and kill them in mass numbers.
