I think it's important not to get the cart before the horse. The purchase of an instrument should be low on your priority list as a beginner. Instead, I would recommend that you rent and take lessons for some time before you start shopping.
With EB, or guitar, or many other instruments, it's not that hard to evaluate instruments when you can hardly play; there are a lot of reasonable quality reasonably priced instruments out there; and the entry cost is low. On DB, however, all of these are different. The high percentage of hard-to-play self-destructing bass-shaped objects and the high prices of decent instruments, mean you're better off, in my opinion, renting for a while.
I was recently able to pick up a good Squier Precision Bass for $100. I don't really play electric, but I could see that nothing was broken, the pickup sounded good, the neck wasn't twisted, neck relief wasn't excessive, etc. An equivalent "cheap and cheerful, nothing fancy but completely serviceable" double bass probably can't be had for much under $1000 and it is very difficult for a novice to distinguish the cheap and cheerful $1000 bass that will give excellent service from the population of $1000 basses that are either beat to death or of abysmally poor quality or will need another $1000 to make them playable.
