Well I went in February of 2001 and I must have paid 45 or 65 then if it wasn't 75. I seem to recall though that I thought it was a bit steep considering what other countries were charging at the time.
Please excuse the memory lapse. I have the stamp in my passport but not the receipt. I do remember getting hit up for 80 big ones on the ODS-IST flight for overweight luggage and I do have that receipt which I sent to the airline to make sure they got the money and not an individual
