No purchase permit required here in oregon, just the 10 dollar fee for the instant background check that you pay for each gun you buy. If you want a CCW it's typically 25 bucks for the required class, in my county if your not a member of the gun club the gun club charges you 7 bucks for the range fees (you have to show proficiency w/ a handgun to pass the class in this county), and then it's 65 dollars for a new permit, 50 dollars for a renewal, and 15 dollars for a duplicate.
*edit* after doing some searching on the net, I found that it's going to cost you about 250 dollars for the class and the permit. Jim Pruett does it in your area, here's his website:
