12-24VDC 2axis controller with joystick input

looking for 12-24VDC 2axis controller with joystick input for a remote vehicle project. I have seen the RoboteQ AX2550 controller used for this application but are there any others that would work?

I will be driving a gear motor for the steering and a 3-6inch linier actuator for the fuel and brakes.

Thanks for any help or suggestions,
