I wish I could I find of those great PRS-300 deals in the US! Not at the stores near me. I did look the other day...
I have attached a screen comparison for you of my Kindle 3 and PRS-505. That will give you some idea of the new screens. You should look at some of the other threads to find a K3 versus 350 comparison. This is my first attachment to a post. I hope it turns out ok for you.
