In going through a new MCM catalog, I noticed something new (to me, anyhow) -- $13 replacement remotes that are (supposedly) customized for particular TVs -- the point being that they include menu access, PIP, and other features not commonly found on "generic" universal remotes. They're on page 55 of the "Summer All-Stars!" catalog, C23B22.
I wish I'd had one of these a few years ago, when the remote for my Toshiba IDTV failed.
