Who makes the best remote dummy launcher?

I don't have a problem spending money on good equipment that works.
But I do have a problem spending money on equipment that doesn't work or worse equipment that kinda works some of the time.
What I'm looking for is a remote dummy launcher system that consists of 2-2 shot launchers and 1-4 shot launcher.
Any help and advice that you could give me would be greatly appreciated.
Thanks
