Would someone please recommend an electronic ink tablet device for reading on?

I have tried reading on traditional light-emitting screens and I find the experience unsatisfactory compared to paper. My ideal solution would be large enough in at least one dimension (portrait or landscape) to view a full page PDF without scaling or horizontal scrolling.

My hope is that someone who already has such a device can speak from personal experience. I find it very hard to trust reviews/review articles.
