I remember buying mine during the LotR exhibition at the Science
Center a year or so ago... had been rather expensive too, about
$100+++. But it's pretty, and it's a worthy piece for collection
purposes. Just a month or so ago, I saw a piece at a store at
Esplanade's. It's an identical one to the one I have, but it's with
a wooden box - which is even better for collection purposes, in my
opinion.
However, if you don't mind it being second-hand, auctions are a
good way of finding one that you'll like. Singapore's yahoo
auctions, or ebay international are good sites where you can find
it at rather cheap prices
