Any update regarding BLN-1 battery?

I'm taking a trip to Europe soon and will need to get some spare battery

Any update on the BLN-1 yet?
any 3rd party BLN-1 that can work with the original Oly charger yet?

Ideally I'm looking for the OEM Olympus BLN-1 about the $30 price range, else I'm going 3rd party.
