Thieve's What to Buy? Thread

Yay, one of these threads! Wonderful, I need some upgrade advice:

I'm in Khaini

lvl 85 Hermit
90 base dex

52 att 3 luk green scarab
10 att 4 luk glove
2 att 6 luk pink cape
22 luk 4 dex red avenger overall
7 dex black snowshoes
9 dex earrings
lvl 70 maple hat
2 luk 2 dex spiegelman necklace

I throw tobies (12 sets)

77M


I need a little more advice than simply "get a zhelm" (already could have figured that out for myself... I want a pirate hat for a while first). The market's pretty expensive right now (sorry, understatement, read:retardedly expensive) so I was wondering if I should wait till the market cools off a bit - selling scrolls and whatnot all the while and getting rich - or if I should bite the bullet, and buy something new and expensive.

One idea I did have was to check out a 5% Slot scroll, but wasn't sure if they're such a slim chance as to be just a waiste of mesos...
