i believe its a £780ish option, so i guess itll be available for around that.
imho your much better off with the rns510, they are available for around the same price.
the main thing that would put me off is the screen resoultion. the 310 is a slightly smaller screen but the resoultion is halved making graphics not as crisp. (images better seen at full size)
guess thats the difference between VDO and bluespot.
