getting past an enchanting hump!Follow

So my enchanting right now is 295...And i am lvl 64 and getting items to DE into arcane dust and planar. Most of my recipes require illusion dust atm. Does anyone know where I can farm items that DE into illusion dust?! they go for about 7g each on my server, where as arcane dust go for 1.5g

Any information would be great, i really dont wanna buy all those illusion dust if i dont want to. its costing about 30g a lvl at this point? is it normal?

wow, I wish that illusion dust went for more than 3g on my server! I would be freakin rich!
