As has been pointed out, the saws aren't the same model. The axminster one is the EBQ (for 240V) and the ebay one is just the Q. So the difference is electronic speed control and brake which are nice to have.
Incidentally I've seen that some festool dealers on ebay are selling at the old prices but with the new deals like 2 guide rails with the saws. I doubt it'll stay like this for too long, so I'd buy now if you want one.
