Depends on your budget.Loads of cassette hubs available,Redline,Bombshell,Ciari,Excess,Sun,Chris King,Odyssey,Shimano DXR.Some oldschool hubs have short axles and don`t always leave enough thread for dropouts/tensioner/wheelnuts.Profile are reliable and all the parts are available separately.Make sure you get a 36hole and not a 32hole hub as getting rims to match can be a nightmare.As for rims,you won`t go wrong with Sun Envy or Alienation Runaway.
