The problem with Saleae IMO is that their current price point is way out of reach for beginners. The software is wonderful (as is the hardware), but it's hard to justify as a newcomer to the hobby at that price point
Eek. I have not looked at their prices in too long! You are absolutely right. My memory suggested Saleae based on prices like this: https://www.adafruit.com/product/378 ($USD 149. Very clearly, no longer the case!
I think Saleae's made way in the low-end market to Chinese Saleae clones that have similar software and hardware to their original models – at similar prices, too.
I think the best approach is to start taking things apart that interest you, and learn along the way. For example - on my blog I use things like arcade cabinets and home routers to introduce some hardware reversing concepts:
There is also nothing wrong with getting some of the arduino starter kits on amazon and using those to learn how to interact with various peripherals, etc.
That is definitely the segment that I have the least hand-on experience with. I've always used the mantis in my shop and not used much else for soldering. Feel free to toss on a PR with some reccomendations/updates!
The Glasgow Interface Explorer [0] is starting to ship out now as well. I got mine a couple weeks back. It’s a neat option for a multi-purpose debug tool.
