Denon AVR-4308CI A/V Receiver Conclusion
If these features aren't important to you, I would look very closely at the AVR-3808CI. On the other hand, if you are looking for an AVR that has pretty much everything you might ever need in the central component of your home-entertainment system, the AVR-4308CI definitely fills the bill and gets my highest recommendation.
Scales all inputs to 1080p
Transcodes all video sources to HDMI

Non-intuitive remote with no tactile response from touchscreen
