enchanting mats do very well too.
and running a few instance groups for gear upgrade will easely get you 1+ stacks of dust and a load of other things (if your not an enchanter, ask someone from your guild to DE em) 20 dust=70-90g on my server.
and i have 3 more stacks in my bank for when i either really need cash or when i need enchants.
edit: those instances will also give you primals and netherweave to sell.
and you can always make use of your trading skills. go farm leather/herbs/ore for a few hours. nets you crazy amounts of money.
