I need help choosing a budget phono stage gift

An older relative recently had an old technics turntable fixed. He is using a Rega carbon cartridge with an older pioneer integrated amp and its built-in phono stage.

I want to gift him a phono stage to help him hear more music from his system.

For $200, I keep seeing the Ifi Zen, Rega Mini A2D and the ProJect Box S2, but I can’t decide.

Any guidance is appreciated.
