I'm looking for a portable media player, but I need lots of space. I was thinking the iPod Classic 160gb, but it is (like all apple products) pricey and would require me purchasing it used. Can you give me any other suggestions of portable media players with around the same amount of space? Also, it needs to have the capability of becoming a transport. In that, I mean that I would like to be able to bypass the internal DAC and use an external one. I know the iPad can do this, and by getting a product like the Onkyo ND-S1, I can do that with a regular ipod. Anyways, if you can shoot me some recommendations that'd be great. Is the iPod classic the best option?
