You could always craft up some caster boots. 5% Max Mana, +20 Mana, High Regen, and some resistances wouldn't be hard to get. Thul runes are also pretty cheap. Just spend a bit of time trading your smaller value items for the crafting supplies you need. Waterwalks are also really good boots, if you can do without the extra mana and res. But you really won't be able to beat a Godly pair of crafted or rare boots.
And some advice on crafting:
1. Use a level 99 character. If you don't have one, use a friend's. If your friends don't have one, cow until you've got one. You can pick up crafting supplies on the way. If you're still too lazy, anything 90+ should work okay. Then only use items you gambled or have bought in cows, since their Ilvl will be as high as possible.
2. Buy sell low value uniques for crafting supplies. Twitchthroes, Frostburns, and Magefists can all go for quite a few crafting supplies if you find the right buyer.
Anyways, hope that helps. And be determined. I've spent plenty of SoJ's on crafting supplies, and it's been worth it IMO.
