It looks like there is a plethora of listings for things looking like that on AliExpress... perhaps all the same, perhaps not?

As far as I can tell, these are clones of the lower end units of the USBee series, that were made by CWAV Inc. through 2015.
--- Quote from: Tim Harvey - Inventor of the USBee ---"Due to these challenges CWAV, Inc., makers of the USBee Test Pods, has chosen to go out of business effective September 10, 2015."

Apparently some software issues arose, which didn't go well... https://www.eevblog.com/forum/testgear/warning-about-usbee/.
They also have some similarities with early Saleae logic analyzers, but the specifications don't line up as well. Regardless, Saleae no longer has an inexpensive version.
So I'm thinking the sparkfun unit and similar aren't a good choice.
Still looking for widely-available low-cost and supported suggestions.

It's a 200MHz logic analyzer with 16 channels, but they also sell other versions of it with different sample rates and channel counts if you need something a bit different. It comes in at about $160, so not as cheap as the Sparkfun one that @sigma7 linked to, but well worth the money in my opinion. The software is quite nice too, and you can download it and try it out before you buy the logic analyzer itself.

I bought the LA2016 analyzer from AliExpress for ~$110 last year, and it is still around that price:

The UI (on Windows) is not very intuitive. You would be quite lost the first time.

I wonder if the software is really different on Windows or something? I've always used it on Mac and I've found it to be pretty darn intuitive!

Not seeing anything else widely available and inexpensive, I purchased a SparkFun TOL-18627 to try out.
The board has a Cypress CY7C68013A-56, so it is similar to the CY3689 FX2LP evaluation board with (what looks like) some filtering/protection on the digital inputs.
I'm guessing the 8 input 24 MHz USBee and Saleae logic analyzers were built around the eval board; I don't know which of those was first, but it appears some individuals made logic analyzers from the eval board too. eg. https://www.instructables.com/FX2LP-CY7C68013A-USB-Dev-Board-Logic-Analyzer/ and https://hanixdiy.blogspot.com/2011/03/cy7c68013a-usb-logic-analyzer.html
