Haybine/ Conditioner

We're old school still mow with a John Deere sickle bar. But would like to find a good used haybine. Our big tractor is a JD 3020.
John Deere,New Holland Case IH dealers are close by. Others are not to far away.
I know this has been talked and beat up before. Easiest to work on? Looking around there is a bit of all models around.
We mow clover, alfalfa, fescue and some others. Most of our hay ground is pretty flat.
Thanks
Dave
