The new Eye of terro box (Son of Dorn) - Worth it for SW ?

Hey all !

I'm starting SW, and to add a bit of ''shooting'' in the army I know most people add tanks, Dreadnough, etc.

Would this box be a good adition or it's too much for what it give ?

I'm talking about the one with 2 Repulsor Executioner and 2 Dreadnough.
