Here is my take.
In my time I have owned lots of different basses. The best one is the one you like playing and feel comfortable with. It doesn't matter at this stage if anyone on here thinks its good or its crap. Chances are that you aren't at a stage in your playing where the particular pro's or cons of a given instrument are going to be on your radar.
You are on a journey and you just need the instrument for where you are now. Buying 2nd hand on here in a given range will get you an instrument which has depreciated and therefore if you don't get on with it you can just sell it and get another with negligible losses.
You are not going to know what you like until you have lived with it for a while and many bass players compromise on one aspect or another of an instrument. It goes play ability over tone or the other way round usually.
So look in here, see which of the instruments change hands regularly and for sensible money. These are your best bets. If you have hands like shovels neck width won't bother you but string spacing will if you have small hands then you will commonly favour a slimmer neck.
Personally I don't think you will go far wrong with a Musicman Sub, a Mexican Fender J or if you can find one a Bass Collection. Yamaha and Peavy tend to be marmite, warwick can be overpriced for newish players. Get a Fender or an MM sub. If it doesn't work it will sell and quickly and you can try something else.
Please don;t forget - what ever you buy get it set up - a set up makes all the difference.
Wishing you all the best.
