There are a couple you could probably quest yourself, like staff of the observers and blued two-handed hammer.
Poison Wind Censor is nice til it procs at 50, doubt anyone is gonna be generous enough to sell it for 300pp tho. I'd probably shoot for Water Sprinkler of the Forgiven or Runewood Great Staff for the plat you have to spend. 11/24 vs. 22/40, the low delay on the Sprinkler is nice, especially if you lack haste.
