John Deere 670

Im doing some research on John Deere graders. Looking at a older 670A or 670b. I see the controls are different. How reliable were they. I know cat is the standard. I just can't afford them. Looking at Deere, champion, or a Komatsu, Gallion. Older Deere seems to be what I'm after. Mainly because my single drop low bed can haul it. Cab height of 10 feet. And they seem to be under 30000 dollars. I'm just looking to fix my roads and work for neighbors alittle. Not like I'm working it every day....
