I used two of the longest 200# gas springs from McMaster Carr. I mounted them close to the base, to keep them out of the way, but most people seem to put them in the middle of the knee. I"m not sure it really makes a lot of difference. With the springs, it now takes less torque at the motor to move the knee up than down!
You can just barely see one of the springs in the attached picture.
