how much do water heaters cost????

Question by ~DaRk PhOeNiX~: how much do water heaters cost????
ok so last night my water heater was leaking water and my whole garage was filled with water going down to the driveway!
i called my uncle and he turned off the hot water so now we only have cold running water and he told me that the water heater is broken and that we need to buy another one!

so my question is where could i find one that is cheap?????
ive looked at home depot.com but thats the only store i can figure out that sell these things????
and how much are they????? im trying to find one that is between $ 300-$ 500 or cheaper lol
