I'm also looking for a LiteOn drive as ONLY a scanner. Burn quality is of no consequence to me since I've already got an LG GSA-H42L (Renesas). Would waiting for the Nexperia chipset drives be worth it, or is the current scan quality of, say, the 165H6S close enough in terms of quality?
Despite my not needing a burner, LightScribe is a plus. The enhanced contrast ratio takes 22 minutes to draw (worth it!), so labeling two discs at once saves a bit of time.
