I really do not know if I can set a price limit and say... scope under this level will or are more prone to adjustment problems. These cheap Simmons Pro Diamonds 4x32mm are $39.00 and they actually track real good. My Bushnell Banner is again, a cheaper (and I hate that word) scope and it works just fine. But I am keeping an eye on my Nikon Omega. Maybe it was just a bad day I was having. But its funny that the other day it behaved just perfect.
