Yes, I ended up buying the Sherwood 4109 at Radio Shack. For $99, it's pretty tough to beat. I also intend to use it to do A/B switching for another pair of M3s at some point when I add them to my gameroom setup (not anytime in the very near future, but when I saw the A/B remote switching, the idea was born)
I've also remounted them at this point using Alan & JC's suggestions and they are far less susceptible to water leaking in (even without putting plexiglas above them, which doesn't seem to be necessary now).
