Dock your iPod for $59.99 shipped

The Altec Lansing inMotion iM600 iPod speaker dock has a list price of $149.95, but until Saturday, you can score one from RadioShack for $59.99 shipped.

That's pretty sweet for a dock with an FM radio, rechargeable battery, and four-star rating from CNET.

One thing straight away: The iM600 is compatible with most iPod models (including the Touch), but not the iPhone. It doesn't charge newer Nanos, either. It does, however, feature a remote, an alarm clock (if your iPod already has one, that is), a stereo input jack for connecting other devices (ah, there's the iPhone compatibility), and a folding design for easy portability.

Speaking of which, the dock's rechargeable battery is rated for seven hours, making it a perfect companion for picnics, the swimming pool, and other outdoor activities.

I already own an older Altec Lansing dock--it sits in the kitchen and gets a ton of use. Here's your chance to score one that's even better than mine, and for a much lower price.
