The Logitech Harmony line of remotes is the perfect solution to even the simplest home theatre setups and prices for these remotes are dropping rapidly, as seen here. Amazon is having a bit of a sale on some Logitech Harmony remotes. They have the Harmony 659 for $77 after $113 of instant savings. Other available remotes include the Harmony 550 for $80 after $50 of savings, the Harmony 880 for $155 after $95 of instant savings and the Harmony 890 for $233 after $167 of instant savings. Out of these four I would say the 880 is the best bang-for-the-buck remote available.
