Like others have said, try as many as you can.
People make a lot of fuss about string spacing, for me at least it is not really a consideration. More important is the construction and quality of the wood.
Yamaha build amazing instruments, as do Ibanez. Every Fender 5 string I've played have always left me a bit urgh. I once owned a USA 5 string Marcus Miller bass that was pretty awful.
I'd save a little more and buy a used Overwater, or maybe try one of their budget models, which are really excellent for the price.
