My view is build a road bike, as you are well aware they sell well on 'that site'
I've been on the lookout for an NSR for ages now, and not seen one I wish to buy, (or the nice ones have sold already)
Basically I am willing to spend up to £3k (can't see the need to spend more) but would want SE/SP spec, with original panels, preferably not resprayed, and in standard colours (no specific colour wanted, ie Rothmans etc) A hard market to jusdge when trying to sell, but from a buyers point of view, I know at any one time, there are 10 - 20 bikes for sale, so they are not 'rare' in my book, and I have the time to wait until the 'right one' comes along.
I've been offered all sorts of bikes, from minters, to crashed/seized bikes that look ready for the skip, cheapest was £1K (and that wasn't the worst one either) up to £4K don't think they are worth that yet as dealers have all the same bikes for sale months after advertising. (why Fastline sold loads at Stafford rather than elsewhere, I have no idea) maybe rose tinted specs, but all look to have been laquered over to look shiny to me.
Sorry for the waffle, but a prospective buyers viewpoint.
As a sidenote, didn't think Les's bike was an SE version. (the Cup bike?)
