I've been thinking about you and the M2, wondering if you had made the purchase. By you looking for a corn head I guess you have bought it. I have an orange 438 corn head that I would sell CHEAP but I am too far south. I haven't used the orange 438 for 3 years. I bought a black head 438. If you can, find one of these heads. With that M2 and a good A438 you can set back in the seat and enjoy the ride. Eddy
