I've almost completely decided to go with the Jensen MP5010K cd/mp3/radio head unit to replace my sony for 3 reasons: it has a "normal" aux input, it has sub pre-amp outputs, and it will play mp3 cd-r's and regular cd's in case i will ever need to play them... an added bonus is that i've found it here locally for 350$ CAD (~200USD) which is quite a good deal considering that the xa-300 would cost me 200$ CAD, and they don't even have it in stock.. so hopefully tomorrow i will have a completely working setup...
Anyone wants to buy my sony cd head unit? didn't think so.. e-bay it is
