Hello, this is my first "deal" and is a subjective opinion so take it or leave it :)
I have purchased one of these myself and think it's a brilliant deal.
You will struggle to get a 16gb mp3 for this price. It has a nice UI and is quite similar to the ipod's. It has a microsd slot allowing for upgrade to increase memory, 8gb card for £10 makes a 24gb player for £70.
It plays almost every video format too with a relatively large but not huge screen. It will last a while as the battery can handle around 30hrs of music playback.
MP3 players can be subjective with a lot of people only seeing the ipod as an option but this is definitely worth a try if you're budget is more reasonable than Apple permits.
