The Gauntlet usually goes anywhere from 350-450 depending on the usual condition/completion/etc. Were as high as 600-700 during lotr's peak. Now would be the time to buy before Hobbit hype kicks up.
idk, as long as its been sold out for, it doesnt even look like it goes for 350 on the bay, so i dont see any steady increases on this piece happening, no where near retail anyways. i have been watching them on there for a couple weeks now.
