Any recommendations?

The ones they used are Robotis OP3, a snip at $14,199 each (https://news.ycombinator.com/item?id=35812475)

The Unitree Go1 seems the most promising among the affordable ones.

Would you know whether it’s feasible for hobbyists to make one of these at home by assembling components

Kind of, see: https://odri.discourse.group/

It is indeed pricey though, IIRC the cost of a Boston Dynamics Spot-like robot came down to around $6-7k. There is still room to drive the price down though.

If you're interested in making one by yourself, you should check out Josh Piper[1]

Probably, but not at the price point of $2700.

It would probably be $25k-$50k and 1-3 years of development time depending on your skill set.

I'd recommend XGO-mini2. It just finished it's Kickstarter funding for the version 2, which runs on raspberry pi. (disclaimer, I did contribute to their Kickstarter) and optionally also comes with an arm.

Bunch of servos in human shapes is not too expensive, available from about $1000-1500.
