I'm with muddy. 20-25% under list price for cash. CIH will add about $5,000 to the price of the combine to finance with them. I don't know where CIH is with interest right now, but I was told they were at 10% a month ago.
I was also told CIH will not guarantee what interest rate you will pay when you place the order. The interest rate is set at the time of delivery. Scary.
Deere will guarantee the interest rate at time of order will be the maximum you will have to pay.
