Round baler opinions

Hey everybody, last year I picked up an additional 40 acres and had a neighbor bale it. I've only done 20 acres of small squares in the past but would like to round bale this due to my busy work schedule. So I'm looking for some advice on buying a used round baler. Locally for sale that I have found in my current price range are a JD 385, NH 848, Hesston 5510, and NH 847. My budget right now is about $4,000, each of these are around $2,500 or less. Anyone out there have experience with any of these balers or have any suggestions on balers I should look for?
