Ready to use and easy to buy options - NOT updated

Hi, there.
New in the community, and looking forward to finding an easy start by selecting a ready-to-use and/or easy-to-buy rover option.
Unfortunately the given ones in the blog are outdated, cant find any of the listed ones:
Robot to Society - SPARK Kit

TT Robotix - Rhino 6x6

TT Robotix - Base 1 Rover

Any suggestion to kick this off will be much appreciated. I would love to avoid hazzles in the basics of the rover,and focus in the software options.
Thanks for your reply.
Regards

You won’t find much if anything. Buy a ready to run crawler and put a Ardurover supported flight controller in it.

The ArduPilot methodic configurator software has a Carisma SCA-1E crawler template with parameters and list of components

Yes, like that. I built one from a Redcat Racing Crawler some years ago and it’s still going. It has a CubeOrange+ in it now.

Thanks, Dave, Lucas. I see, I will find my way. Thanks again
