Target stores are having their spring clearance sales these days. I just bought something like you are looking for, at 75% off original price. SONY Universal speaker dock:

The Target near me had a few left for $15. That's a steal, even if this is less fancy than other docking stations.
The Amazon listing is a little more informative.

I haven't unpacked mine yet, but it says a cradle to hold the player and a connection for charging.
