i don't think i saw a single post asking what you would like to do with the computer? because this is entirely the most important decision for buying the laptop, do you need it for school, just for internet, do you need it for a special program only available on mac, what else do you use it for?
personally i need the MBP so i can run logic studio 9, and i wont mess with using a hackintosh or breaking licenses to make music, if i do that then the music is made on stolen equipment, just kinda a meh situation, but i also need the portability because i go to school aswell so i cant have a desktop. something to consider
if you just need it for school and you don't want to spend the cash and you wont go on some sort of guilt trip for piracy i think the hackintosh would be the better investment, but remember you get what you pay for, so if the thing sucks, well....
PS: gratz on raising 1200$ lol i know when i was 14 i couldn't hold onto any money
