I really could not equate a $ value to performance ratio but up to 4 years ago I had been running the AI Modules 3A for 9 years traded it in on a Modulas 3B both with the JC boards and the improvement was significant and to tell the truth was just hoping for it to be as good as the 3A, so I guess I won. Now with all that said the time it took Al to build the 3B and get it to me was 16 months and since I was retiringI lost confidence in them and switched brands.
