I do have to charge for doing a Lite-On drive, because I'd like to buy the Spear by Maximus, and it's a pretty penny to buy the connectivty kit + Spear. Runs about 68 dollars with shipping to me.
The last guy who had me do a Lite-On provided a connectivity kit, which I just soldered the wires for free. But, he bought my spare MS25 drive I pulled from my RRoD box.
I have another Samsung MS28 drive lying around that should be in working condition. Someone sent me a box to repair the 3RRoD syndrome, and then disappeared off the face of the earth, but refused the package when I sent it back. I never fixed the box, because he never sent payments, so I kept the box.
If I get enough orders, I'll start doing Lite-Ons.
