I find the 3800 quite ugly with its front loading CD slot, it also has the resistive screen of my 8800. DAB is quite nice but you'll have to run the antenna somewhere.
Thinking about it, Apple or not, the SPH-DA120 would probably be my choice at the £300 mark. Without the IOS integration it still just operates as a normal Pioneer head unit. You could load up both USB ports it offers with USB sticks.
Id be worried how the 3800 would fit also, its a lot squarer than the SPH.
Maybe have a peek in Halfords and see which you prefer, they used to have them on show for you to fondle the last time I went in.
Either way, USB seems to be your only requirement so most headunits will suffice
