I was at Walmart the other day and just happened to look at the remotes offered. I always look, even though my own Flirc is bricked, I like to think ahead. And I did!
This PAIR of remotes was available for on $4 US. Notice they have both volume and channel selectors AND a separate directional pad at the same time. And one of them is backlit!
I was hoping to show them in-line, but this will have to do: see the attachment!
And get to Walmart! :>
