Wake-Shaper or Wicked Wave

I'm looking at getting a Ghetto Gate or Wave Gate or whatever you want to call it.
Does anyone have any experience with either the Wake Shaper or Wicked Wave?
This is for my 2002 Supra Launch

Are there any others worth looking at?
This is what I know
Wicked Wave is around $300 for one side or $500 for a pair, made out of thick plastic
Wake Shaper is $550 but works on either side and they say can be swapped easily, made out of aluminum
