Bjorn/Bruce - thanks for the useful links and comments so far. The current demands don't seem to demanding, maybe I'm being to concerned about nothing here so a simple approach maybe best to start with.

Exactly - I'd like to try to make the psu a single rail 12v input so it can go on my maintained supply or be used in the field. It doesn't look like a particularly demanding aplication although I wish I'd decided years ago to make the battery bank here 24V or even 48V.

Yes, although some of the monolithic PSU modules are pretty noise free if you take care with a little post filtering and pay attention to the grounding / track layout - in fact I *seem* to get get better noise performance using dead-bug construction than tracked PWB. I haven't taken delivery of my Epay thunderbolt yet so I'll probably wait 'til it shows up in case it's a dud.. but if anyone is vaguely interested in the outcome I'll post a link to my website when its working.
