Hello and thanks for your comment &advice 
I had looked into the Lewis Creek Nightingale after reading other people’s previous posts praising this lap harp. I haven’t heard one being played, but it’s appearance is in my opinion supierior to the somewhat clunky outward design of the Christina.
Unfortunately I live in the UK and there is no distributer for Lewis Creek here (and I know from having a few teething problems with my current it pays to be near someone who can easily repair and replace parts when things don’t go to plan!!)
