Hi,
welcome to TalkBass.
This question gets asked a lot: which bass for a beginner.
Check out the Basses forum, there are several threads about this.

Not to put you down immediatly, I'll try to give some advice.
It is hard to choose a bass as a beginner, and it is harder recommending one.
Golden rule is a cheap one off course. You'll only know what you want after playing sometime.
If you learn how to play bass, you'll know what features on a bass you need/like, and what is possibly for the certain sound you are going for. After a little bit of experience you can go to a music store and test several basses out, to see... hear what suits you.
So cheap but still decent, most likely when you become better you're going to get another bass. And maybe for nostalgic reasons you can keep your starter bass around.
A lot of cheap brands get a lot of praises around hear like SX, Squier, Yamaha, Ibanez,... . These companies don't make junk (opinions may differ) and they offer instruments at fair prices.
A lot on this has been discussed here over and over.
Now okay, suggesting is fun.
My personal favourite cheap bass, and to recommend for a beginner is the Squier Classic Vibe '50s Precision Bass.

I play bass for 9 years, and I recently bought one of these because they are so much fun, so cool, and sound so good. Also incredible quality for that price.
(My main bass is an expensive one.)
I did a search for you on this site (Search function in the menu above.)

Good luck trying to find a first bass.
