The HK Audio active systems. LUKAS XT is the smallest for small crowds, Projector is the largest for big open airs.
Always the sound of a good studio monitor, the difference is weight and price only. Check it with a good CD at your local dealer.
More expensive but with a much better sound: The active systems of Mackie.
All these systems are easy to handle, you only need EQs because the acoustic of the rooms where you perform.
