Found a 1994 Diamondback Response Elite on CL for $50, I just spent another $50 and about 16 hours of work making it a rider. Like this one^^^^.

It's a fast bike, it weighs about 25 with the oil suspension fork, which soaked up a rough railroad track crossing like a champ today. It's double butted True Temper chromoly steel. I painted the fork a matching color to the frame, (Duplicolor car paint).
I'm really liking this one as a rider!
