Also, those were just the three first ones from memory + a quick google, there are probably other options - but i doubt you’ll find anything under $150. Pedals are not cheap, except when mass produced - and a programmable dsp pedal is by definition niche.

Another option, for people willing to hack a bit, is that the FV1 dsp chip is used in a ton of pedals, and is pretty hackable if you wanted to load your own code: you could find a cheap pedal that uses that chip and hack it.
