Hi Paul, I recently purchased a Keces P8, which has dual outputs, so I have one output powering a 9V switch and the other powering my 19V Nucleus. You may specify voltage outputs depending on your needs. I purchased the unit from Keces USA (link here) and it was shipped to me rather quickly from Thailand. Price was $599 including shipping. Couldn’t be happier and not a mortgage killer! 
Also, if you’re a masochist, you can read all the posts on this thread! Cheers!
