Thank you everyone for the input. I managed to get the DXG today and I am super in love with it. It's older and has different software than what I'm used to, but I can always use something like Duokan if needed. The screen is just the perfect size- I love the page turn buttons... Works well enough with the PDFs I use (nothing complicated, just scanned pages of novels).
It's a shame Amazon calls it obsolete and won't do anything related to the DXG anymore!!!! It's great for what I need it for!!!!
