I'm planning on getting my girlfriend an iPod HiFi system for Christmas but I'm not sure which one to go for. Does anyone have any recommendations? She has the original 4:3 video iPod.

I've been looking at these on Play and they all seem decent but I'd much prefer to go on recommendation. I have about £150 to play with, perhaps a bit more.

iSymphony M2
Logitech AudioStation
Griffin Amplifi

I'm leaning towards the iSymphony at the minute, just because of all the formats it supports.

EDIT: I should point out that I really do want an HiFi with an iPod dock rather than just a fancy set of speakers.
