sansa dock excellent
I have the sansa dock and have been using it at home for several months now and I am very happy with it. The sound is very good for such a small unit. I am not an audiophile so take that into consideration. I have tried 2 other sets of speakers( non powered) and was dissapointed. The dock comes with lots of extra's that come in handy. I got mine from Amazon, free shipping and no tax!! can't beat it. I think the if you are going to use it for your office it will fill the bill for you.
