Someone recently mentioned something called “LHT00SU1”. It’s primarily a logic analyzer, but it has one analog input. (I’m not into EE, never used scopes, just randomly found a discussion about it recently)
I don't know if they still have a hobbyist discount, but when I bought mine they knocked a good chunk off the price after I emailed them and told them my plans for it as a tinkerer.
No disrespect to Saleae's Logic as even their 1st gen product was indeed outstanding value (and may still be at the current price point; software front end is well executed). But to be sure, there's still a significant hardware gap that sets it apart from "the real deal".
