trying to find an alternaotor for suzuki car

I can not find an altornator for my suzuki esteem 99, 1.6L, i'm looking for 150-200 amp alt for a DECENT price, hopfully under 200$ I found one shop that offered me an alt for something like 600$ that did like 300 amps, but I really didn't need all that power, I can't not find anything over 85 amps. I need at least 150. also, if you could reccomend a good bat for that amp range, my battorys on it's way out, it's a couple years old now.
