Hi, I have been having some problem with my alternator lately and now it decided to call quit.
I already tested and everything so its a definate because the battery is brand new also.
I went to my local autoparts and I found one for around 80-110 depending on brands and what not.
Then the gentlenment said they have 2 different alternator for this MAKE and MODEL.

So my main question would be.. how do I know which one to get?

Thanks a ton guys!

Take old alternator in and match it up to new one. Higher amp alternators are generally physically larger.

It is also important to match the electrical connections (called "clocking"), to new or reman'ed alt.
