If it's not going to be too over priced, take an orginal. I have seens some problems with the 3rd party ac adaptors. Problem including
- Plug does not 100% fit
- Unexplained burn marks on the laptop motherboard.
- People not checking the output before plugging it in and burning the laptop
I was about the go a 3rd party AC adaptor myself, however after seeing a few with that second problem come into my shop, i would be directing you to the orginal or 100% compatable AC adaptor. The Universal ones are trouble.
