Query: Klipsch v AltechLansing

Having owned Altec inMotion speakers for XMRadio/Pioneer Units, decided to try the Klipsch iGroove SXT Speaker. Looks good, but ends there, the iPod Touch 3G falls out of the dock (does not lock), the power supply failed within hours of setting it up - sent it back and ordered the Altec inMotion Compact iM310 for the iPod. The iPod does not fall out, the unit is totally portable/foldable, deep bass, it charges the iPod, and can be used with batteries, unlike the Klipsch plus a 2 year warranty to boot - what a great deal only $65 v $150 for the Klipsch from Amazon.
