I need all the moneys I can get at the moment. A new MP3 player must be purchased this week before going on holiday!

That's a point. Could anyone recommend me to a nice little MP3 player for around the £100 mark? It must have a nice screen (size doesn't really matter), good sound quality and volume, at least 16GB of storage (may fall to 8GB if I see something particularly good), AAC  playback would be a real plus (so I don't have to re-encode all my music), and it can't be an iPod.

I've spotted a few Sonys and Samsungs but so far nothing has really jumped out at me. The Samsung YP-Q1 would be perfect if it played AAC but sadly it doesn't.
