which baler would be best?

I am a small time operation. We bale maybe 2500 square bales a year. We are looking to upgrade our baler. I found a New Holland 273 and a 276 for sale. Both appear to be in field ready condition with no known problems, and the sellers seam to be honest. The 273 is a supersweep with 3 joint PTO. Both have a kicker. Which model would be more desirable? We would be baling 1500 bales of wheat straw and remaining bales would be grass or alfalfa. It should be noted the combine has a 36 ft head and makes a big pile of a windrow.

Thanks in advance.
