Custom hay baling in my area has steadily gone up over the past 6 or 7 years from $15/bale (cut, rake and bale) to more than $25/bale (C,R&B) with string tie. When moisture was available for growing hay it was always "I'll cut and bale your hay when I get around to it" from the custom balers. When the drought was kicking our butts it didn't matter when they got to you because you didn't have any hay to bale so you had to buy it anyway. Always a dilemma. I finally picked up a fairly new NH BR780 for $15K which turned out to cost me the price of a new one before I got all the bugs worked out. Bought a new 12 wheel rake at the beginning of last haying season and finally got all the kinks worked out of it at the end of last season. If it hadn't been for my old NH851 AutoWrap last year I would still be in the field because the BR780 was in the shop most of the time. That old, ugly, chain baler just keeps on going. Man, those new green Megamouth balers (at $40K) were starting to look real good around August of last year while my red one was in the shop.
Anyway, what I'm suggesting to you Bull is buy what you can afford but give serious consideration to new. Even new will break down from time to time but at least you will have someone to grab by the throat when it does break, not like me where the only one I could grab was me.
