While I HAVE looked these up on the AH, I'm not a frequent auctioneer and I've decided to get a price check before I rip myself off. I'm pretty poor and need the gold LOL!!!!!!!!!!!!
1) IK chest armor (842 armor, 147 STR, 80 VIT, 76 resist all): http://i.imgur.com/riQ0w.jpg
2) IK gloves (355 armor, 222 STR, 10% crit chance, 283 LPS): http://i.imgur.com/5sPXB.jpg
3) Blackthorne belt (514 armor, 194 STR, 108 VIT, 259 LPS): http://i.imgur.com/EqNOX.jpg
PS: it seems like someone could make some real money on ads if they built a good auction-house price-tracking website. they could then charge $$$ to access the real money database.
