I have a ricoh 5125a and i think its satisfactiry to me. However, due to the fact that some newer xbox will not play +r disk, I am thinking about buying a dvd-r drive. However, I want to retain the speed of quick erasing of +rw. I wonder if a -r drive can do that. Also, what speed do you guys burn at? I have heard as the cost of 2x or 4x disk is substaintially higher than 1x, and people tend to buy 1x or 2x media to save some cost. How much is a 2x -r media? Is it comparable to a cheapest +r disk that can still be written at 2.4x?
