Back in Split we played around with another interesting Altec Lansing system, the InMotion IM510.
Although the product has been around for a while, it drew our attention because it's a San Disk's Sansa speaker set. So, in case you haven't fallen victim to the iPod craze, this portable four speaker system might be a nice choice, since it is one of few noteworthy Sansa accessories.
It's powered by 4 AA batteries which can provide up to 24 hours of playback and an AC adapter is included. Of course, the speakers recharge your player and you also get a USB pass through cable for syncing which should make your life a bit easier.
The device is very rugged and you also get a carrying case with it. The build quality and design are also very good.
In case you're interested, check out the product page, here. The MSRP for the US market is $99, and in the EU it will cost you 99 euro.
