Pete,
The initial bass purchase is often just the start.
So I concur with Mr. Back, your budget should include purchase of bass, then possible/probable set up, string, pickup purchase and a decent bag, or case.
I hope you're pockets are deep, or you've still got both kidneys, either way it can prove an expensive journey, but worthwhile.
6 basses, 5 pickup/pre's, multiple string purchases later and I've finally settled on what I play.
Obviously there are those who's initial purchase has been "it" with no further outlay required......b@**¥#%:s!
Often some nice instruments on sale here.
Best wishes with your search
