Lol, aye, insurance is a must!
The boardmans, decent spec but don't like the look of them. Am a bit partial to a Specialized mtbs (as are the jakey scumbags that seem to follow me around with bolt cutters) hence my liking for the brand, also as you say, really nice lookin bikes.
Getting it on the Cycle to work scheme so tax free. Think when you take that into consideration the Diverge Sport fella looks a decent buy. It's got decent reviews etc.
