Thanks for taking my suggestion to heart, but IMO there's seriously no need to make this item THIS expensive. All it really allows you to do is to keep from having a room full of chest for all the stuff you can't burn for EMC & don't want to void. It costs experience to use and you can't automate it to my knowledge [unless maybe through AE?]. How is it you consider it so OP? With the inflated cost to create one, it's basically useless when you're at the level where you can craft it.
Might I suggest you make it uncraftable and either add it as a quest reward or perhaps as bag loot?
I was just doing that because I had no better recipe. If you give me a better recipe that I think is more fair, I will add it in. Also I like the loot idea, but I still think there should be a recipe, so if you(or anyone else) thinks of one, put it here.
