I'm considering one of the new Onkyo receivers. The 898 or 797 that aren't quite available yet. Anyway, I wanted to hear from owners that have had their receivers for quite some time. How do you like 'em? Would you buy one again? Does the display dim over time? I had one (another brand) that the display text dimmed until you could barely see it any longer. I'd like my next receiver to be my last (yeah right). Thanks.
