Amazon has the 4 channel 100Mhz Oscilloscope for $399 with free shipping. This is the lowest price for this scope on Amazon. Matches the lowest price in last 5 years according to triple C. Usually $500. This model is hackable to 200MHz, and will then identify as the SDS1204X-E in firmware/on display. That would, in a roundabout way, make this nearly 50% off a $775 oscilloscope.

- $80-100 Hantek 6022 series USB PC oscilloscope https://www.amazon.com/s?k=hantek+6022[/url] ] (Probably the best bang for your buck if you don't mind needing a PC to use it)
As someone else suggested you might find an old CRT-based scope on Craiglist or FB marketplace, but just about every single one I've ever encountered was worn out and needed calibration or a lot of work.
Also, FWIW, I also own the 200mhz 2-channel version of this Siglent and it's excellent.

Lots of options on ebay.
Try Craigslist. You might come across one from an estate sale (i.e. retired engineer) or startup closing sale/giveaway. I've seen few times of old tech instruments being advertised at super low price from an estate sale on CL. My guess is that family members have no use nor interest in using these when their loved ones passed away.
Triple or quadruple that budget if you want a reliable and accurate one like a Tektronix that has been tested/calibrated and confirmed to be fully functional.

Well, maybe. I bought a TEKTRONIX 2213 2-Channel / 60MHz for $65 a few years ago... seems to work fine.
