We go through a number of magic items, and we are allowed to trade items for full value, or sell them for half value.
Far from making me cringe, I think that THAT is about the best way for the GM to really control magic items. You want to make your own? Sell for half and make. You want this one? Keep it. You want to trade in for a list of what's at the store? Here's the list. (I mean, I'd probably charge a surcharge for realism...)
I like that a lot. I'll suggest it. It will not be used (by the other GM's in my group).
However, I do agree in general about sharing.
On the one hand, in one group I'm in we're considering pooling a share of our treasure to give the blaster mage a +6 int item way earlier than he could afford it. On the other hand, I fully expect to be recompensed as time goes on. Of course, part of that recompense is gonna be the fact that he took the magic item creation feats and I didn't... But that's another story.
If people consistently kept magic items, or if I were the bandit in question, I wouldn't have an issue pointing out to the group that indeed I do feel cheated. And worse, my character is starting to feel cheated.
Then I'd take everything from everybody one day and leave the group with all their loot. I mean, that character could never play again, and it's possible that the GM would make him into some sort of nemisis (With a LOT of magic items), but hey, I like the story.
