Help choosing AT build controller, please

I need to build an AT. I am still a little confused with the various boards on the market and the various versions of controllers available. Without going overkill for a simple 2-3 servo AT, which would be the best option to choose:
Pixhawk px4 2.4.8
Pixhawk 2.8.4
Pixhawk 2.4.6
Other OTS options, etc

I have no idea which version is which or even which is the latest. I have old eyes so dredging through a ton of online forums and documentation isn’t a good option for me so thank you for any advice you can provide here.

Thank you

Hi Larry,

Any of those Pixhawk versions you listed should work fine. The Pixhawk v2.4.8 is readily available on eBay or GoodLuckBuy/GoodLuckSell for under $60. I have 5 of them and they work great!

Good luck!

Thank you very much, Greg. This was a huge help for me.
