Ive got the Alpine 9880r, very nice headunit, set me back £140, but you've also got buy the iPod cable to go with it, costs £15-20. But with the cable you gain full access through the headunit, so you dont have to go trawling through your iPod to find a song/playlist.
Good thing about the headunit is that the backlighting is orange so goes nicely with all the other lighting on the dash, ill get a picture late if you wish later on ?
Alpine X100 is what you need son providing you have an ipod...
