Linear actuator for outboard

[adamjs16]

I want to use PyPilot to construct an autopilot, for my outboard on my dingy.

In terms of linear actuators, it seems I have two options. Both have built in rudder feedback and end of travel switches.

1. pcnautic bare tiller drive
   
2. Many options are avaible on Aliexpress (some of which listed here)
   

The pcnautic looks like a good unit and seems like the safe option. However, I have recently lost my job and I'm looking to save money. There are so many options on Aliexpress, it is hard to know where to start. None of them have many reviews so it is hard to judge the quality.

I would appreiciate some advice on which option to take. I would like to know if there is much of a difference in quality between pcnautic and aliexpress. Could anyone recommend or send links to actuators on aliexpress that have been tested? I know a few have been discussed on the thread I linked, but they are all different, which has just made me more confused.
