if you got money, get the Bone Razor and a good offhand
if you dont have money, and dont have high lvl friends, get a Gloompoon/PSD
if you dont have money, and have high lvl friends, get a Phinny spear/PSD/Burning rapier.
I have a ton of weapons on my rogue alt and i have to say, having options is fun

Personally, with kunark close. Id get a Phinny spear and burning rapier with some nice haste you'll do fine and push out some nice dps to level with. Both are fairly easy to get and cheap.
P.S. My rogue has: Phinny spear, burning rapier, PSD, Gloompoon, Serrated Bone Dirk, PGT, and something else i can't remember.
