Yeah, I'm trying wheatgrass myself. Finally Faith swears by it and highly recommends it. He has some incredible stories about the healing benefits of wheatgrass.
I think I am going to get a juicer that does both wheatgrass and veggies and fruits. If not, then one of those little hand cranked jobs and another juicer. My juicer now is on its last legs (Juiceman II... heh... but it has served me well through several fasts and continuous juicing for more than five years). But I'm getting a dehydrator first, so I can do raw foods when I come off this 30 day fast.
