I bought a 100 from Shop4tech, paid about 32 after shipping and tax, about 8 of almost 50 have become coasters, but and this is a big but about 4 of those were because of a program error, it burnt a copy of the movie or at least what the program thought was the movie. The other four can still be used to back up data since I stopped them from finalizing. I give them about a 4 out of 5 for now. Also I bought some of the ones from Fry's when I first built my computer and they arent very good, they are called Great Quality but they scratch easily, and therfore skip during the movie, I give these a 2 1/2 out of 5. Also, on a side note the Dvd-rs, that I bought from Shop4tech.com, play great in my PS2
