New from MS and need some input

[Matador]

Hello to all. I'm here for a specific reason adn I hope someone here can help me. My 9 YO son is RC crazed, has been since 4 or 5. Very mechanically inclined for a child to the point he can operate effectively a mini excavator https://www.youtube.com/watch?v=i7bzno3HqPQ.
He really wants a RC excavator for Christmas and I am lost. I can't justify spending the money I see some of you spend on builds but I also want something operable and decently made. Do any of you have any suggestions in the $200 range that would work for him?

Thanks in advance for the help.
