So, I'm checking out equipment lists and, I'm not seeing a lot of ways to boost my unarmed attacks aside from the Amulet of Mighty Fists, which is quite a bit more expensive than a basic magic weapon (5k for a +1 as opposed to 2k).  Are there any real benefits to being an unarmed-focused monk, or to get cheaper bonuses with unarmed hits?  Or would I be better off scrapping the amulet and getting a real weapon?
