If I'm not wrong, Ranking Sports do sell Crafter acoustic basses. The price is around ur budget i think. Other than that, they also sell J&D and TGM acoustic basses but at a lower price. *I don't recommend J&D and TGM. I've tried before and the action is quite high. Crafter's are better.
Another shop u can consider going to is Davis Guitar which i've recalled seeing a Fina Acoustic Bass selling there before. Going for $400. However, I'm not sure whether it is still around...
And maestro guitars too. They do sell acoustic basses but i'm not sure with the price.
