Going to look at this system tomorrow, it has the 180 sweep that goes into a 24ft alley that goes to a model 91 headgate from my understanding. The pics i got of it aint the best so its hard to tell exact condition. My question is how well do these hold there value. I was told its 9-10 years old and theyre asking like $800 less than what i can buy new. My thoughts are buy new before doing that, but im hoping to haggle on the price once i get there if it checks out in good working condition. So getting back to my question do they hold value that well if they are in good shape? Just seems high to me so thought id ask for input.
