You may consider an early R two series. I have had an N6 and an R70. Both were good, but the two series is a lot more service friendly. The extra $15,000 is worth it to me. Hope you find what your are looking for. I live east of Enid, OK.
Doc M, nice to see some one from the neighborhood. I'm just north of Enid. We just got a '84 N6 but don't have many acres so the extra money for a 62 was not an option for us.
