Alpine Head Unit

[waloshin]

It's too late and I am too lazy to register at another forum. Is it worth the differences to buy the Alpine CDA-9886 over the Alpine CDA-9884? Would their be a noticeable sound quality difference. What i am looking for in a Apline Head Unit, a decent price, sound quality, ipod control, HD radio compatibility, bluetoooth compatibility, Satelite Radio compatibility, a decent display. I was thinking about the Apline iDA-X305 , but if I am correct their is no cd player, so I would probably have to add a expensive cd changer and i really don't want to do that.
And would the 2nd Gen Ipod touch work with these head units?

Thanks!
