typical cost to repair liquid damage on MBP

I spilled about a tablespoon of windex onto the keyboard of my 1.66 i7 MBP. Of course it was on when it happened. I turned it off and flipped it over for a few hours. I was getting ready to go out of town when it happened so I had to close it up and take it on a plain with me. When i got to my destination the next day I tried to start it up and it was dead. I have since read all of the I should have done, but didn't.

I was looking to get an idea of the different cost scenarios to get it fixed. Like if it needs a new logic board, etc... I understand it might be better to get a new computer but I don't have 2800 for another 17'' MBP.

Does anyone have experience having a MBP repaired after liquid damage? How much did they pay and what was wrong with it? How long did it take? Was it extra to retrieve the data?
