You can also take a look at the cylinder condition (internal). If its not scratched up, rebuild kit will put you back in business after a good cleaning. Time vs. money and a roll of the dice no matter what you do.
I haven't checked lately, but a rebuilt cylinder used to be within a few dollars of a kit, and the rebuild is guaranteed. I would not kit it........and you need a hone as well........unless there is no other choice.
