Ok. Everything was received from The Malt Miller today. Massive thanks to Rob who included the sodastream adapter he had tested for free. Top man.
All the parts from The Malt Miller look to be great quality. The regulator is a serious chunk of brass and the tap looks great. I did, however, order far too much gas line.
Everything was assembled as per the King Keg video -

This is where I had a bit of an issue. The sodastream cylinder didn't seem to be connected. As per the video I wondered if the pin wasn't protruding enough. A
Unfortunately trying to unscrew the adapter from the regulator I'd found I'd done it too tight and my adjustable was about 2mm too small to unscrew. Balls.
I tried to see if I could encourage the pin from the bottle. This was when I realised that one of the spare o-rings had decided to join the o-ring inside the adapter. I popped this out and tried again.
Pssssss. The sweet sound of success.
I pumped the sanitiser through the tap and then added my priming sugar and racked the beer (see White IPA thread) then purged three times with 30psi of CO2. A final addition of 25psi to seal the keg and I tucked it up in the shed.
In conclusion, this is an excellent method for someone who doesn't have easy access to gas. I've no idea how much of the sodastream cylinder I've used, but hopefully it will last 5 brews.
I also thoroughly recommend The Malt Miller for the equipment and would have said that regardless of the freebie. The price of the regulator, especially, is much lower than I'd seen elsewhere.
