[Spell] Best Equipment System?

Level 12
Feb 19, 2009
I've been shopping around, and I've been looking at inventory systems on the site. I'm trying to decide on the best one based on my needs. What I want is:

- Heroes can only have one type of item (Weapon, Helmet, Boots, etc)
- Generally certain heroes can only have certain weapons (Only archers can use bows, only mages can use staves, etc) this isn't absolutely required tho.
- A simple system, not a separate inventory screen, just a revamped version of the inventory system that's already in the game.

What's the best system that fits that description?
