What is the difference in the 2 effects named below? and also are these any good, as they are reasonably priced per pair.

Chauvet DMX Sensation
Acme Jaguar

To me they seem identical lights, quite liked the demo video on chauvets site, but the ACME is cheaper.
If they are same effect different badge, then I may as well go for the Acme.

Or would you suggest some other kind of DMX Dual head pack with a reasonable price tag?

Thanks in advance

OK if you don't use it too much, once a week and replace it after 18 months.
