Thanks for the feedback.
I agree the Glide A is the best option, but since we are being pushed to buy 5 of them for a total of $90k, when we only need 1, it does not make economic sense. That's why if we were looking to get a single GAL AT400 conversion kit at a reasonable price; or any other option that would work. Someone mentioned there is a Monarch option as well - can anyone confirm?
