Ok as promised here is a glimmer of hope for especially UK owners of the D25/S
Battery - Akku für Sony BP-2X BP-2EX CCD-VX1E - 19.90 EUROS + 6.00 EUROS P+P = 25.90 EUROS (approx £19.50 all in)
let me first preface this regarding the battery;
Yes, you can do a google search for '
sony BP-2X' or similar keywords, and it will return seemingly bonifide results to stores and ebay shops (
which end up being the ebay shop fronts of the actual uk battery companies also had issues with) in the UK which have them down as being in stock and available. let me warn against this if i may, having now ordered no less that from 4 of these stores (battery firms in the uk) and ebay shops listing it, they
ALL take your money, dont contact you until you contact them, then they all tell you its out of stock.
I personally dont believe it, i think this an old product, an abscure product that they simply still have on their database and are too lazy to remove!
This battery and the UK dont mix - trust me.
I ended up sucessfully ordering it from here, it was listed as "Akku für Sony BP-2X BP-2EX CCD-VX1E", a german ebay seller, who i have to say, was probably the most pleasant and helpful ebay seller i have ever dealt with and i have dealt with thousands!!!
It was here within a few days, working perfectly, all with great communications, i have to smile though, as i even got a free pen and pack of haribo included in the package! 
There was no import or customs to pay on such a low value consumable, and it worked out the same, approximate cost as the hassle inducing UK companies.
Power Supply - 12V DC 400mA Fixed Voltage Regulated Mains Adaptor - £9.99 + £2.98 P+P = £12.97
From my emails with Ken at ALO, i/we understood from the beginning this was always going to be a little tricky due to the requirements of the power supply here in the UK, its reversed polarity and pole/jack dimensions.
To cut to the chase, Maplin electronics (whom i am sure all UK'ers know about) where very helpful after me emailing them with the situation and specifications needed. they pointed me to this
(their part number: MG81C)
After receiving it this morning, and being very careful which tip to utilize, and indeed, ensuring i got the polarization correct (reverse) worked flawlessly
You receive 6 interchangeable connectors with it, none initially attached. for the Sony D-25S the one you want to use is the red coloured tip, which is 2.1 x 5mm, not only this, but ensure the connector is placed on back to front ensuring negative polarity, no fear as you do get a small basic diagram showing how to achieve this.
I hope this helps at least one person having issues sourcing the basic parts needed to operate this costly, but beautiful player!
