Oh, full support! I love those! Another reason to keep those - sometimes I have to dispose stuff like iron swords with cool enchants on them to clear up echest space or something. But - hey, I know it seems greedy - I don't want them going to other people. Less competition, you know? But my best bet is always chucking them down that water chute or dumping them in lava in pvp, which is very out of the way and I'd most likely be killed by those rampaging diamond people down there. Jeez, are they aggressive. You'd think most of them would have thousands of dollars already. But this isn't my point... So yeah, support!
