Depends on what you mean by "best value for money". If you're after something cheap, there are any number of low end solutions that are pretty ok for the price. LRP seem to have a few good ones in lower price range.

If you're after a top end speed control, we do the MRT MX Pro for $250. Small, lightweight, very powerful and smooth. Local 12 month warranty. Details available HERE purchase-able from HERE .
