Most potentiometers will only rotate a certain number of rotations (often about 240 degrees), making them inappropriate to steer a swerve drive. We used a Hall-effect sensor that simulated a continuous rotation potentiometer for our kicker last year. I believe it cost about $50 from McMaster-Carr, but I don't have the model number. I did a bit of browsing, and found several devices of this type under "angle sensor", but I couldn't find anyone who posted a price on the web site.
