iPod speaker dock thingy suggestions

[Big G]

I'd like to get 1 of those speaker dock things that I can put my iPhone in and listen to my tunes when working on my desk at home. I've seen a few around which have a battery also which would be nice to take to race meetings.

Any suggestions on good ones you know of?

I'd like to spend <£30 if possible.

I bought a cheap thing off ebay about a year ago, powered by 4 x AA or a AC adapter (available off ebay for £2-3)

Sounds is pretty good for the money, and it fits in my haulier easily enough. Best part is theyre around £10 delivered. Link -
