Mike,
Thanks for the kind words!
AutoCAD and Paint Shop Pro do most of the work on these drawings, and notepad takes care of the text.
I just move the mouse around, hit some keys, and copy/paste text.
I will pass on the compliments to those 3 applications! 
Seriously though, thanks for the message!
BTW:Do the drawings with the Black Backgrounds appear better than the older ones with the White Backgrounds?
The reason for the change to Black Backgrounds is because I now use Black Backgrounds in both Model Space and Layout Space, within AutoCAD - whereas a few years back I had Model Space in Black, and Layout Space in White.
My Eyes are thanking me daily for the change!
Scott
