Graeme,

I did the same 4308/3808 decision making thing back in Feb. I opted for the 3808 because comparing features didn't get me over the hurdle for the price difference. Of course the 3808 gives a bit less in the area of bragging rights and the smell of testosterone in the air, but it saved me ???, so the offset was fine.

The 3808 is a real beast in it's own right. I set it up with a wireless bridge and all works perfectly.

I don't think you'll miss the 4308 if you go for the 3808.
