Looks like they still make it.
Multifunction flashlight might be cool too for younger.

my oldest is 7 I'm hoping she gets into it. I really want to learn this too because of useful to know electronics repair
Very doable. That TV off gizmo might be a little advanced. And you may want to learn good soldering techniques from YouTube, etc to help younger ones.
You might even look into auditing a class at your local community college or trade school if you're interested in the troubleshooting side of things.
TBH though lots of people that troubleshoot these days do less and less component level. Lots of "board swapping."
That's not to say you can't do so.
If we get into another "great depression" hard skills are tough to beat. Saves on repair/replacement too. My wife and I have fixed numerous appliances/devices.
I want to learn how to do more than just board swapping. I look at it as an investment with the skill set and if I can get my kids knowledgeable as well I'm giving them more opportunity for the future with everything they learn.
I learned a lot through my military training.
They crammed electronics and calibration into a 10-month course and some continuing ed afterwards.
LOTS of great resources to learn out now. Wish I could point to one in particular. Maybe Adafruit is a good starting point, or Udemy.
It is definitely like a muscle though. Once you learn it, use it. (Or the skill will atrophy.)
Thanks I'm going to do some digging. It looks like the local schools near me don't offer much, and the only classes I've found are for kids. While that's my aptitude I don't think they'll let me take classes lol.
You do anything with @Bitcoinveterans?
You bet! There seems to be a TON of online content these days. You can learn from places like MIT even.
Found a sample playlist on YT that would help with the theory end of things. Traditional classes would mix in some simple soldering and circuits as you go, but theory is important. (Below).
Haven't done much with Bitcoin Veterans yet. I should. Thanks for the nudge.
