Before you send it out, check with an Apple store. I just bought a used as-is 2010 13" Macbook Pro with bad logic board for next to nothing. I decided to take it to an Apple store this past Monday after gettng quotes of $200+ to $300 from various repair shops who do board level repairs. Apple quoted me $280 for the repair and I figured WTF, it may (or may not) be a few buicks more than one of these fixerupper guys but it's backed by Apple. The $280 is the flat rate to fix "whatever needs to be fixed for anything other than liquid damage."
I brought it in Monday and got it back Wednesday and this is what they did for the money:
Replaced the logic board
Replaced one of the speakers
Replaced the battery
Replaced the screen and clamshell top.
The top of the case which was beat up, scratched & dented is now shiny and brand new looking. The display which had 2 or 3 bad pixels is now perfect. The battery which was about 800 cycles is now new. Plus I have a 90 day warranty from Apple. All in all not a bad deal because I was about to spend AT LEAST $200 with one of the folks listed on the internet who I didn't have any real clue at to their rep.
