I don't know what U.S. prices are like but you definitely need to craft better shoulders/bracers/gloves/neck. Picha's advice is good, whatever you spend the money on, make sure it has all res and high damage. Some items to consider outside of the crafted ones:
1. Change rare ring to a good Zuni Pox (will add 55 + 60+ All res).
2. Change Zuni Boots to one with higher int and 70+ All Res
3. Trium with vit (your goal is to be in archon mode as much as possible, so get vit there instead of APOC, keep the Apoc trium for other builds if needed).
4. Int/Vit Inna's
5. 6 CC 250+int Armor Tal Rasha's Helm (used to run with that before my mempo and is not very expensive)
6. Tal Rasha's Allegiance, with CC or Attack Speed (AS tends to be cheaper).
7. Life Steal Weapon.
