That is quite a rant Lowell. How could they be months behind on progress payments and simultaneously only owe you $25k (of $337.5k) to complete the machine?
Are you still being sued by AMHD? Has it been settled? If not, I think IMHO that you should preface any diatribe with the fact that you are being sued by the company you're diatribing against. Some of people who read these posts might not be aware.
