What about the Stein of Moggok? It's not got any Cha on it, but the +10 Int is not bad and it is basically Enchanter-only due to the quest. As long as you are not trying to melee, it also makes a nice main-hand companion to the Crude Stein for that
all-important bar-fly look and comes with three charges of Light Healing.
Even if you don't keep it, the wiki shows it selling for over 300pp in EC, which will help you afford your Cha gear.
