Those old three screws were prone to stretching when used a lot with full magnum loads that is why they discontinued them and beefed them up. If you are going to shoot it thousands of times you should stick to 44 special or equivlent loads. If your friend is happy with $500 or less then that is all you should pay for it. A gun is only worth what you can get for it. I once bought a beautiful winchester for $50 because that is all the the guy wanted and you know what it is worth? Nothing, because it is not for sale. By the looks of the EE I could get $900 but its still worth nothing because I won't sell it. They are only worth what you get for them when you sell them.
