you could do a lot worse than one of the sale condors, they will still measure you up and swap the stem length to suit you, anything else that is easily changed like tyres/chain/saddle/seatpost/crank length they will change if you want to upgrade (i would get the izumi chain/carbon post and whatever saddle you like). if you want a wheel build though you will probably have to wait unless they have anything on display that you want.
i had a look at the willier pista and it seemed way overpriced for the parts spec, probably a harsher ride than the pista too, after all it is a track bike rather than a road going fixed/ss
