As the Captain of the Luddite Society, I am still using the Oehler M33 that I bought in 1978!
I have upgraded to the Skyscreen III screens (1990 vintage?).
That Oehler set up cost me an entire month of Marine Corporal pay at the time (about $300).
I am hoping to use this machine until I croak!
If I were starting over, I'd get a Labradar.

got mine in 81. Still use it today. Bear
