Siglent is definitely a value-for-money option. I'd noticed a few years back where Keysight had started creating some nice offers in the education space for entry-level oscilloscopes, but they simply don't have to try as hard as their competitors. So many modern oscilloscopes from even basic brands (also see Rigol) are simply incredible devices well beyond the needs of an average hobbyist. Everyone sets their own needs/budget and honestly for me I've never beat the value and need for much beyond my old Analog Discovery 2 that I grabbed at a sub-$200 education discount way back when...
Good luck!

as an EE engineer, I would have not expected this on slickdeals
Since this will draw experts, could someone educate me a bit? I'm getting into tube amp repair/building (mostly repair/restoration currently), and see all the pro guys have an oscilloscope on their benches. I know one use case is to see the "signal" of the amp, in the context of tube biasing, to kinda know when the sine wave is "right". I don't have a background in electronics or circuits or anything, so I'm quite naive. What other use cases are there for something like this? What differentiates a $500-$1k scope whit a cheapo $20 USB type thing? What are different "channels" used for?
What it shows is what the electronics is doing at a particular location in the circuit. If you have multiple channels you can look at multiple areas at the same time which can make troubleshooting easier. A good example might be having an intermittment problem and you suspect its a capacitor, you could probe the capacitor and the problem area and see if the errant signal in the target area only happens when the capacitor is discharged etc. Or say that after a particular branch goes from low to high, you're supposed to see that reflected in a different place 100ms later... hard to do that if you don't have multiple channels. You could see that it changed, but you might not be able to see how long after it was triggered did it chance... or if its a pulse you might miss it completely if its not being monitored.
other than the # of channels is the sample/display rate, the voltages/current/time period it can handle.
I was curious and this appears to be supported by sigrok:

Dave Jones , man… Dave Jones… that's all you need to know.
Ha ha, nice!

Nice deal. Last time I was seriously considering a scope I think it was a heathkit: it's been a few decades - amazing what a transformation digital has made of our world

Do you know what a multimeter does? A multimeter measures electricity, or electricity based signals. It gives you a number.
This does that, plus it gives a picture of how that signal changes over time, (volts - electrical pressure, amps - amount of electricity delivered).
Some of them can do a lot of other things, like compare multiple signals simultaneously, and do complex math operations on them.
It can do this on incredibly short timescales, down to millionths of a second.
This signal picture lets you know how your circuits are behaving, or whether your digital signal is being delivered or generated properly.
It's a groundbreaking tool for people who work with electricity or digital signals.
yeah, kinda new here

I will say though, why have they been consistently expensive for an entry model over the years? I guess that is more a function of demand/supply than anything.
