From reading both product links it appears that using the converter adds convenience in that the TV doesn't have to be switched between inputs. The partsexpess link had this to say at the end of their product description.....While this product will convert the composite RCA signal to be viewed on an S-Video input, the signal will only be as good as the original composite signal....which answers a question I had about it's benefits. Probably worth 5 bucks anyway to reduce switching by one click.
