If you are going to do a lot of this you might want to consider using 3X or 5X RAM as it will save you a lot of time copying the files to the HD. Otherwise you read at 2X.
If you go this way the LG works very well and is your only option for a few months. After that there will be 3-4 new drives. The LG is a very good drive for writing as well.
If you can find an old Liteon 166 ROM drive this will also read RAM at 2X. Pioneer 107, 108, and 109 will also read RAM but they cost as much as the LG and they do not write.
One last tip, do not install InCD as it will interfer with your ability to read anything writen by another drive.
