Xbox 360 CD Drive help

I have the Halo 3 edition xbox 360 and ever since i had my xbox, ever since the halo 3 edition came out. my xbox has been screwing over my discs. i did a little bit of research. and i dont know how to tell like what kind of cd drive i need. and i read something about someone with the same problem and sticking the new drive in. and having the xbox say stick the disc in a xbox 360 console, somoething about software or whatever. where could i look to find what drive i need. and when i stick it in. what software or whatever i need.

ok thanks for letting me know. umm do you think i could get like descent amount of money for it. its in perfect condition its just screws over the discs?

Honestly you wont get much for your xbox 360 if you sell it to gamestop id say like 60 bucks considering its been 5 years since the console came out. They will rip you off, so honestly jsut send taht **** in and get it fixed. register it online, request a repair. if they charge you to fix it then just have them sned it back and fix it when you ahve the money or save up money for a new one. I ove gaming on consoles, but sometimes its situations like these that make me happy i own a PC. good luck with your xbox dude, i ran into a problem like this before.

point loss for avoiding sticky no chance

but i ran out of my warranty. i only had a 1 yr warranty and its been over a yr. but dont i have to have the warranty to send it in to get a repair? but if i have to, ill just save up and get a ps3 which i want instead of xbox 360. and just wont play the xbox. but thanks for the help. really appreciate it.
