john deere 100 big square baler

hi, i know this is going to get bashed right away, sinse my other research i have read on these balers are bad. but im looking for honest opinions from people who have used or own these balers. im just looking at possibly adding a big square baler for hay sales. how bad are these balers for dry alfalfa/grass mix. ive seen some for sale with 40,000 bales that tells me they must work to some extent. we have round and small square so not looking to replace them. just looking at baling around 200-500 big squares depending on sales. thanks
