hi all, i'm thinking about buying my friend an ipod mixer for his Isiah this december. i'm having a hard time telling the difference between all of them and was hoping someone would know some benefits or drawbacks of these models, or at least know a website that i could check them out. i'm looking at the Numark iDJ Mixing Console, which is about , and the MixPod DJ Mixer, which is like . anyone heard of these? like them? hate them? thanks!
