What kind of roller skates should i get? ( what do you recomend?)?

OK. so every friday i just go to a regular skating rink which is used for stupid kid party's and indoor hockey. I use rental skates there, but i want some of my own. not the cheep ones you get at target and Academy. i want the real stuff. iv looked online and stuff but i still don't know what KIND of skates i should get. like indoor skates is what i need but should i get roller derby ones? even if i don't play roller derby? Or what should i get? whats the difference between all skates? and where can i get the best? thanks a bunch.!
