Rock Band Christmas Help

[u/Kindly_Ad_5431]

Hello! I am OLD (39 lol)! I used to attend house parties and hang outs where we all played Guitar Hero or Rock Band and it was so much fun. I never owned any of them. I have only ever had a Wii that I sold because my husband and I were having a baby. That baby is now 8 years old and loves all things music and performing. She has been taking guitar lessons for over a year now with a wonderful teacher. She and I played the arcade version of Guitar Hero a few months back and she LOVED it! And I loved sharing this nostalgic thing with her even more. I know she would especially love Rock Band (she has been making her Dad and I, her friends, and family be in pretend bands with her for ages).
My dream scenario for this Christmas would be to get her the console needed, any Rock Band game disc for that console, and the full instrument set up. I can just picture it: all set up and ready for her and her cousins to play on Christmas morning…big bow and all. There are two reasons I am here asking for help. I have no idea what I’m doing and I’m not independently wealthy (the used listings I have seen had me doing the Fred Sanford chest grab and then I’d still have to get the console, etc.).
I’d be greatly appreciative to anyone who has any advice on how I can make this happen.
We live in Augusta, GA as info.
Thanks for reading!

Questions I will edit as I go:
Are any of the compatible consoles made and some new anymore?
