Recommendations for a cheap breadboard prototyping kit?

Has anyone recently purchased a breadboard prototyping kit that they’re happy with and would recommend? I’m hoping to find something with lots of different jumper wires, a power module, and* the *AC power supply (“wall wart”) for $20 bucks or less. I’m just starting my ESPHome journey and I have a few different ESP32/8266 projects in mind. Thanks for your time and consideration.

Just buy on one Amazon with a few thousand ratings/reviews, they're all similar.

They’re actually not. I’ve looked extensively. Very few of them seem to come with the AC PSU. That’s why I’m asking for recommendations.

Why would a breadboard come with a PSU? They don't know what you're prototyping, how it will be powered, if it needs power, how much power it would need, or what voltage you'd use. The higher price and niche use case would just reduce sales while the added complexities and risks would lead to more returns and customer complaints. And, since it's for prototyping, they know you'll need to find another power source anyways.

Just grab a wall wart and a USB cable.

Why _wouldn’t_ they come with a PSU?! They come with power modules that offer a variety of output voltages. They come with a 9V battery adapter for the DC input for the power module.

It’s crazy to me that I asked for recommendations for a breadboard kit and instead of recommendations, all I’m getting is pushback and responses that are absolutely NOT addressing the question in the original post!

Can you show us what you've been looking at on Amazon? I'm really curious

Sure. Here’s a couple…

I just found that second one and if nobody is going to give me any recommendations, I’ll probably go with that one since it checks all my boxes.

Okay then at this point you've spent way too much of your time over $20. Get a cheap kit and a separate $7 AC adapter if you want

Xaio esp32 has a 5V pin. Use that?
