Greg, I will prepare a document and get back to you.Corrected... I think I went by the dropdown on your site... I will read more and probably have some questions, like the number of bells and whistles in the various versions, since I think at first people would be wanting to see more different versions. I think you can also change the motor/prime mover.
If there is a document I could read instead of bugging you let me know.
Greg
Regards
Peter Lucas
