They're kinda niche devices, with some kinda expensive hardware like very fast ADCs, a decent FPGA+CPU, some fast RAM, and a lot of effort in the software development for a product that likely sells in the tens of thousands of units.

For cheap, I'd recommend looking for something like pic related, a bog standard analogue 20MHz dual trace model. Digital doesn't really matter unless you need to capture signals that don't happen often, or need to do accurate measurement. There were hundereds of manufacturers doing similar models, buying used ones made back in the 80s or 90s is fine.
