Looking for iPod 30-pin speaker dock

I realize the iPod Classic is practically prehistoric, but I still love mine. It holds a huge amount of music and still works great as a house "stereo." Unfortunately, the Bose docking speaker failed this past winter after 10 years of constant use, and the backup JBL On Stage Micro died this morning.

I've searched everywhere and all I can find are used devices in "good" condition from sellers with low ratings. It seems the one device that Apple built to last is rendered useless because no one is making 30-pin speaker docks anymore.

Any tips or links? Ideally, I wold like a small footprint, like the JBL.
