I have a Sony Vaio (PCG-2C1L) desktop I am working on. Looks like I need to change out the optical drive. The model of the drive is UJ-875. I found a few on ebay for good prices but want to make sure it is the right optical I need. Can someone give me a link to ebay or other to the right model?? As I said I seen a few but just want to make sure its right.
