While we're on the topic of line-outs for iPods, are iPod dock lineouts worth it? I'm in no financial shape to be purchasing an iMod for my iPod, but considering that it is now my portable source and bedtime source, would it be wise for me to purchase one of them? Obviously I'm looking to go as cheap as possible (insert random ALO joke here), so if you think it's worth it, from who should I be buying?
