My friend and I are so excited about this bot that we're actively looking for AI grants to apply to for funding the purchase! The price is incredible for what you get, but we both work in the public sector :/
Consider the ROS simulators first, and look at the platforms used in RoboCup events. There are better platforms than Talos or HECTOR around.
It can take years to get a basic bipedal platform operational, and in general it takes 3 times as long to tune the software/firmware. Unless you see actual proof of platform operation for more than a minute, than take any claims as marketing hype.
Could also try a cheap servo hexapod or turtle-bot kit first, as stable well-studied platforms are easier to code on. =3
