BigHammer: Also had confirmation on the battery this morning. Thanks Lee!
I ordered one around Tuesday 11pm so didn't think I'd still be in with a chance, but happily had the following nice email from Adriatica this morning:
"Many thanks for your order. These have been very popular in the last 24 hours! I have run out of stock but managed to get a few more, so hopefully i can send this out to you late this afternoon, otherwise it wont be until tomorrow."
