I want to buy a new head unit in the next few days but i'm unsure of which one to go for so i'm looking for ideas.

I'm running subs and components so i'd like something which i can control those with but also i prefer head units that give you separate bass, mids & treble control rather than having to use the e.q to adjust those values.

I already have a Sony one with usb but i'd much rather prefer to buy a Pioneer one with the usb input at the rear.

Can anyone recommend any that i should look out for on ebay etc?

Thanks
