I would add my voice to those suggesting that the item recieved is NOT a heirloom.
Fancy peasant hats, boots and dresses are a far better way to reward donators... why?
1) It doesn't give you a chance to pay for in game advantage
2) clothing, however weak, makes it possible to show off in-game that you donated
3) We have enough heirlooms as is. Lets not flood it again, and have fasader steal them back.
I shall however donate.
