O woe me! I broke my Xbox 360. What do?

[Staple2]

About a year ago I started getting those Open Tray errors when a disc is inserted. So I did some googling, found some easy methods to fix (restarting worked), and basically pwned that bitch. Usually took me like 5 minutes to fix it whenever it occurred (once a month, maybe).

Then the errors became more frequent, and about a month ago they happened every time I engaged on-mode and/or inserted a disc. The fixes stopped working so easily, and it started taking me anywhere between 5 and 60 minutes to get it going every single time.

Last night it stopped going, even after 3 hours of tricking it. I went to extremes. I vacuumed the disc tray. I pounded the shit out of it. I even performed a minor exorcism. It still gives me the ye olde Open Tray.

What do you think I should do? New Xbox 360? Repair? Laser replacement? Wtf will this cost me?

EDIT: I have tried breaking it open to have a look at the laser/rom myself but I can't get to it, because I don't have that special little tool.
