Buy.com now has the Altec Lansing inMotion iMmini portable audio system for the iPod Nano and iPod Mini for only $19.99 plus free shipping. These have been as much as $99 at Buy.com and are currently $130 at Radio Shack! There is no sales tax (except to CA, MA, MD, TN). This is a compact, well-reviewed (4.5 of 5 by over 130 reviewers) iPod speaker option. New Google Checkout users can get a $10 off discount for signing up and paying via that service. Of note: I have these and like them; they are compact, can be powered by batteries, and travel well.
