Look for a second hand 5er, I know there's a few cheap ones (Squier and Yamaha) on fleabay at the moment.
I've had a G4M LA P 4 string bass and it was utter rubbish. Pickups and electrics were shockingly bad, neck was ok, body made out of paper - super lightweight and dented just by looking at it. The bridge kept becoming loose because the body wood is so soft under tension of the strings, it would pull up. 😪
