Logik micro hifi -should I buy one???

Hello all!
I've been looking for a new hifi. I have an mp3 player so I like the idea of a usb port.

Currys has a few by 'Logik' and I wondered if anyone knows if these are any good?

Or can recommend a good alternative (Sony, Panasonic etc don't have the usb only a 'music port' are these any good?)

Thanks, all advice will be appreciated!
