best really REALLY cheap reverb?

Hi everyone!

looking to add a reverb on my board and i just want (at least) one good reverb sound (dont care that much about type for now and customisation, it just has to be big and good enough) and i want to spend less than 60 or 50 €.

i came to the conclusion that there are 4 contenders :

i play an hss strat on a katana amp (and an audio interface when i'll figure out how to make it all sound good...) and have other effects (fuzz, bd2, phaser, delay, weird fuzz-autowah-filter).

i want to get a big psychadelic reverb sound (like tame impala) i'll use normal 'room' level reverb on my amp

thanks for the upcoming answers/comments
