Reading the forums i feel i read more negative than possitive on all the products.
Everyone has their favourites and everyone will avoid anything to do with electrics they had a problem with some time in the past. You won't find any F1s using Castle and no one at my club will use Novak having seen too many of then go bang in the past.
Personal favourite is the Hobbywing Xtreme Stock, although it's not on your list. Of the four you have listed I would only choose the Tekin or Reventon, if you can stretch to the price then go for the Tekin, if your budget isn't that great go for the Reventon.
