30k on average for a stack of Tuna sushi.
Hauberk seems to be floating around the 4-5 mil mark (reasonable I think)
Monster Sig's getting up there again. Used to hover around 1 mil, last sale was 2 mil (damn it people the monster sig is not that good, stop buying above normal AH prices)
CC hovers around 34k. Which considering its bsts most commonly used jug tends to get expensive.
Most HQ staffs seem to be floating around the 3 mil mark. Not as good as it used to be but still reasonable. Too bad I didn't keep my funds when I sold my lu shang. I bought 2 HQ's and the rest of my NQ's during the christmas rush. Ouch
Tatami Shield seems to be hovering around the 4 mil mark. Much better then the 9-10 mil I saw it going for around christmas.
Astrals were floating around 1.5 mil the last I checked. Damn I should have sold mine during christmas and rebought them now :)
Those are the only things I've really checked on recently. I haven't checked the prices on vermy's or the scorp harness, sniper rings.
