I believe the thread starter wanted something that doesn't cost more than 1k...
I have a PS5, and really like it, to a certain extent. Only for single note harmonies. And it sucks alot of your tone, but a true bypass looper will the the trick.
It can't handle more than one note at a time though, so if you're looking to harmonize your double stops, look else where.
Else where as in Eventide territory, there aren't any cheap harmonizors that can do that.
