Plat Farming for a level 51 Monk?

[xassis]

I am level 51 currently, and I need a place to get some fat stacks of plat. I've put days (over the course of my character's lifetime) into farming Grach, and I swear if I have to look at another Kunark Goblin's face I'm gonna have a meltdown.

Not looking for EXP, JUST plat. What's another good place to get fast plat from? Hadden seems to be always camped, and HG's aren't very fast since there are always people there.
