I just got the D-25s recently as well, but decided not to buy the battery because it's expensive and I don't think I'll need it in a truly portable situation where I have no access to an AC outlet. But, I did check ebay for these batteries, and they do have them from time to time. In fact, there is one now here. This person has a number of them, and is selling them one at a time. I believe they are all new. He's in England, which isn't all that far from you.
