Don`t bother I saw this too, and quickly rang the number.(I only live a couple of miles from sutton).
I enquired about the A1000, only to be told by the seller it was an A500, with a 1/2 meg upgrade,and somehow he thought it made it a A1000 !!.
I dont know how i kept myself from not laughing down the phone.
Ignorance is BLISS !
