First of all I am 68 and have eyes that are also in the early stages of cataracts.
I have a SWFA HD 5-20 x 50 illuminated and love it. I like everything about it. Great turrets easily zeroed and they line up EXACTLY on the witness marks when tightened. Reticle is useful without being overly busy. Both turrets and reticle are Mil/Mil. First focal plane keeps stadia spacing the same under all magnifications. The tiny illuminated dot in center is a bonus as it won't block view of intended target in dim light. I hunt coues wt in S. Az with this scope. The tiny red dot sure helps with seeing the crosshairs on an animal at first and last light.
Jon A did a great write up on this scope:

I bought a condition B illuminated 5-20 and it was flawless as was a condition B HD 1-6 illuminated. Skylar, at SWFA, said they are very discriminating on what scopes get assigned the condition B. Bought another scope in condition C and it had a mark on elevation cover, that was all.
Or you can go here and buy a new one.

For $899 that used one would be something worth trying.
