Also try not to buy keys, or at least wait until you have enough money to not be worried about losing some. Even now with the improved chances of perfect weapons dropping, you can still get some real crap stuff from chests.
Keys = great gold sink, but even though I know this, I can't go past a chest anywhere without opening it... I neeeeed to know what's inside lol
Hope that was helpful, I'm off to farm some more chests *sigh*
