I have a NH 575 in the barn (paid for) that I have not used in 5 years, every option on it but a kicker. I too went to round bales, I have one large customer that buys everything I make, picks it up in the field and pays me yearly. I should sell it but if I did, my luck would be a need it, so it sits in the barn and the cats sleep in the feeder.
Personally, I despise small squares almost as much as I dislike dealing with horse people. My customer is a cattle rancher.
