Land Appraisal Cost?.....Southern Oklahoma

Looking at buying a piece of property in Southern Oklahoma(Bryan County) North East of Durant; and wondering if anyone has purchased or sold property around that area and if so - Would you mind sharing what the appraisal cost or if your familiar with appraisals what a ball park figure on the cost to have 160ac appraised?

Feel free to PM me if you don't want to post in open forum.

Thanks,
