Really tempted to buy this 3d scanner, $200 off

Nah, get cheaper from aliexpress - shipping date suggests it is coming from China anyways. Aliexpress is usually cheaper than Amazon.

Giving this a lot of thought
I give mine a 3 out of 10. It’s ok for basic stuff, but the touchscreen is a bit finicky and it has some serious aliasing issues with high frequency stuff. What would you be using it for?

Consider this instead on Ali.

It's not a highly rated device but it's better than the amazon unit by the same maker and your stated intent isn't too rigorous.
You will have to spend big bucks if you want a relatively good scope. So this is prolly a wiser way to start. If you enjoy it and find it useful, then you can shop for a better scope - prolly used to keep the price down.

The prime day price was $180 so close to the aliexpress price.

I have a 16 circuit in the house and an 8 in the barn. I really like it. Will help at tax audit time too.
The 1014 is at $207 on Ali today only. Prolly trying to compete with Amazon. Never gunna beat that for an entry level Oscilloscope with a basic signal generator too.

As I said before, the reviews are not great but that's because the reviews are comparing it to a $5k lab scope. For what it is, I think its a good buy. Even comes with 10x Probes. Says it is 100MHz but 10MHz is more realistic. No worries about klugie on screen buttons

I think that's exactly why I suggest something like this. Anybody who can make parts on a mill or a lathe can learn basic electronics using an oscilloscope.
At first blush, they are complicated instruments. Perhaps even intimidating. But like other complicated things, a smart fellow can learn to use one and learn some basic electronics.
I don't advocate a scope like this for guys who are already proficient. These characters should be looking for something much more costly.
In a way, the scope is your book!
But yes, there are lots of beginner videos and books out there.
Fundamentally, an Oscilloscope allows you to see how voltage varies with time. It does that by creating a graph on its screen with voltage on the vertical axis and time on the horizontal axis. Both the voltage and time intervals of the graph are adjustable so you can see what a slow low frequency signal like your household voltage looks like, or the higher frequency music being played on your speakers, or any other voltage that varies over time.
A multi meter will tell you that your 120V wall outlet produces an AC Voltage of 110Volts, but an Oscilloscope will show you that it is really producing a 60Hz 170V sinusoidal voltage. A Scope can also show noise on the voltage caused by various devices that are plugged into it. You can't see that or even know about it without an Oscilloscope.
In general, I have found that the "for dummies" books like you mention are actually quite good at getting going on just about any subject they cover.

It would certainly be a start. I have not read this one so your mileage might vary.
Edit - the book does have introductory Oscilloscope content.

The bigger 1014D unit with buttons is now 200 with free shipping. A dual trace 100MHz digital storage scope plus a signal generator for $200...... Hard to believe.....

Even if you derate it to 50MHz (or even 10) it's still amazing. I almost want to get one just to see it first hand with my own eyes!
Here is a photo of one of my Scopes (a Fluke) looking at the power input to a spindle motor. Sorry about the glare.
I think this is pretty representative of what the 1014 would do, but the display on the 1014 would be much better than the old screen technology on the Fluke.

I agree. Do you have one of them?
Edit - The 1014 is a nice upgrade for the money. Buttons and controls are a good thing on an Oscilloscope, and it also has a signal generator built in.
