GIK Acoustics or another option ?

I have read on here for a number of years from other members on how good GIK acoustic panels are.    I had some extra money, so i contacted them , had several emails with John and he suggested  some panels for me.    I paid for the panels back in July and got a email sometime in August that the company was having a hard time getting supplies due to you know what, but the order should be ready by the middle of September.       September came and went...and have sent a email every few weeks and i get the same answer each time....that it will be shipped out soon.        Here we are in the middle of October and still nothing.

so my question is.....are they really that good and worth the wait....or is there another acoustical panel company that is just as good that can be recommended ?
