Best additional reader for a 52246?

I have a 52246S writer, and wonder wich reader would compliment this one best, for being able to backup most anything. I have an aging Aopen dvd that I will retire soon.

Thanks for Your input!

If you need DVD, the LiteOn drives are great. Another burner is also a good idea. I have all the above, and the 52x burner is the best reader/ripper of the lot.
