Help need a MP3 or iPod, 8GB or higher?

I would like to know your opinion because I am saving up for either, I live in the UK and one available in Currys, Comet, Argos or ASDA I need one with alot of memory at least 8GB one because I need it to store music albums not lodes but I need one with memory for a lot of room for movies on as I am going to America and need one so I can have at least 10-15 1hr30mins-3hrs movies. Please help I was going for the iPod Clic 120GB but its only another �50 for 160GB I think from Argos so I need to know if they are good?
