Went in to Argos to pick up a Winmau Blade 4 after reading the recommendations on here. They brought out the Blade 5 from the warehouse and said it's replacing the Blade 4 in Argos. (Blade 5 is not even on their website yet).
I'm no darts expert, it's been many years since I owned a Dartboard, however thought this might be a good deal as the Blade 5 is over £30 everywhere else right now.
It's possible this might not be the case in all store, but worth a try.
