The remote
The remote, if it's the same one that came with my 56TXi is a huge best of a remote. Fully backlit with a 2 line lcd display that costs around $165 to replace(last time I checked). However, I've found that the remotes from the newer Pioneer receivers can handle most of the controls and are much cheaper to replaces since they are minimally backlit and have no lcd display. Unfortunately, those receivers do have a lot of functions and the oem remote does make it a lot easier to use. If you got the receiver for free, then that at least makes it a bit easier to decide. I'll agree with everyone else though, I replaced my 56TXi with the VSX-23TXh and I know I gave up a lot in the power department.
