Bicycle Tunning. Need help.

Well...not to mention i'm kinda tomboy since I love sports...but anyway.

I'm about to buy a new bike...however I dunno whats good and whats bad. Since i'm not a professional person and i'm not using it for a special purpose than going to school,

Any suggestion of what kind of bike I should buy? Example what brand, with what break system along with the chain system..blablabla

p.s. I know EXPENSIVE 1000$ BIKES R GOOD...but...I'm not paing 1k for somethign I use 10mins a day.....more or less. I just like to drift around =P..

jus get like a mountain bike or sumthin to me it doesnt matter what brand aslong as its a good bike lol

get a 200 dollar bike, that seems decent enough.
