Twinking a rogue...

[Doors]

Haha seriously, where'd that cash come from. But yeah, spend most your money on an FBSS. You can go bargin basement with weapons and dual wield a gloomwater harpoon and a polished steel dirk.

Other than that, cheap items off the top of my head include:

Exec hood - 300
Hero bracers - 300
Banded armor
werewolf skin cloak - 250/300
Serp bracelet - 50
Dwarven work boots - 300
Probably can find rogue class armor items cheap.

The haste is worth the cost and beats out spreading your cash around trying to get the best items for all slots.
