who sells the best combat lightsabers with sounds?

I own a force fx ESB vader saber that I'm having upgreded to ultra fx combat blade, I'm going to buy many more & I don't want to have to go through this upgrade every time.
Who else makes a full contact lighted blade with sounds thats made for combat?
Can anyone help me please?
Thank you.

There's a company called Hyperdyne that makes one similar but tougher than the Force FX sabers.

It's pretty expensive though and I don't know anyone with one.
