alpine ivad 100 vs ivad 310

Just curious on  everyones thoughts for dvd deck selection in the alpine world.   As is sits i have just purchased an alpine theatre 5.1 amp  and am looking into something new as far as a video deck goes  the old alpine 9835 i have wont control the amp tuning.  I know of the smaller screen size on the 100 and the lack of inputs compared to the 310 but is there anything else?  thanks. 

I would go with the 310 nicer unit I think. The only downside to the 310 is the ipod adaptor for it is slower and costmore.
