Hello acapollo and welcome to MR.
If you wait for the perfect reader you'll never get one. When I started looking around for mine I decided to take the plunge and get one I felt most comfortable with. Now I have learnt heaps more about readers, files, formats and so on and am more equipped to get the next reader.
I am fairly happy with mine and have not regretted the purchase one bit. But then again, I only use it for reading fiction as I still read non-fiction and textbooks as pBooks. I guess it all comes down to what you want from a reader.
Have you checked the
matrix or this
subforum yet? Might give you some more ideas.
