Perfectly reasonable thoughts, John.
Happily, the value of the Video Systems 3 class was above most any classroom training I have received, so in retrospect, what I paid for the ISF class years ago is a far greater tragedy compared to THX reducing the cost.
I do intend on pursuing the L4 Audio Cal when it becomes available as well, having attended the LI, so the above mentioned arrows left only a small bruise.
Thanks for the replies John.
