I have this one, and extremely happy with it...Monitor Audio has a very good sounding unit, the I-Deck, don't know the price for the newer version, but the previous version is $99.99 Saturday Audio (
www.saturdayaudio.com). This unit sells for $150 to $200, so $99.99 is a great price for Monitor Audio sound. If you check on the internet you will also see excellent pro reviews of this product.
Monitor's I-Deck also has a 3.5mm input jack for Walkman, and other audio devices with a 3.5mm out headphone jack; so you are not just limited to the I-Pod. And as an added feature it has a video out (S-Video and RCA Jack) so you can see your I-Pod's videos on your TV or Projector. A USB and Firewire connections are provided so you can connect your I-Pod to your computer without having to disconnect fromt he docking station.
This is one of the best sounding with the widest connections I-Pod docking station in the market.
Keep in mind that docking stations cannot do what a good receiver can do, so if money is no object, get a decent receiver with an I-Pod docking station (I recommend Marantz and Denon), with a good set of speakers (there are many to choose from, personally for the price I like PSB Image Series), so you can take advantage of multi-channel, surround, multi-zone, and other sound/video processing options.
If a stand alone unit is preferred, then go for the I-Deck.
