I'm wondering if the media for these units has now been established firmly and if the units themselves are reliable. I'm thinking of when a VHS film is too large to fit on a normal DVD.
If you like $10.00 coasters - they're great. More time needed to validate reliability of hardware and software although no problems in purchasing dual layer burner - they will still work as single layer burner. Using a program such as DVD Shrink you should have no problems in fitting re-processed VHS onto a single layer DVD.
