gamerswonder still got 2 in stock last time I check. They are $30 each. They are on holiday at the moment so even if you order now it won't get shipped until 13th Feb. I have ordered from gamerswonder before and they are reliable with fast shipping.
Otherwise as some other member has suggested Bamboogaming is another place to order from. But note that they ship from China so the delivery time will be at least five days.
