After spending a whole lotta time looking at ebooks (and blabbing about it on the internet) I came up with an elegant and creative solution.
I'm using my Nook again.
I don't actually have that many Amazon ebooks and I can read them on my tablet. Everything else, hey ho for the Nook. Now I just have to remember to routinely plug it in so I'm not sitting in the barber shop waiting for my appointment and my book says "Insufficient power to turn on".
The best part? It was free because I already have it. Sometimes the simple solutions are the best.
