My first choice for a glossy presentation-quality disc is Taiyo yuden watershield dvd-r's . It's a high quality disc with very good compatibility with burners and DVD players. The print quality is likely to impress, too. Don't know your definition of inexpensive, none of the glossies are cheap(and be careful here, you could waste a lot of time and money handing out nice-looking bad discs that won't play on a DVD player:doh:), but I find they're worth the cost, and reliably burned at 12-16X. Don't burn them faster even if your burner thinks it can:disagree:. Best deal I see currently shipped to San Diego is http://www.mediasupply.com/tydd5mwsh16-100.html. They don't often go much cheaper from what I've seen.
What printer are you using?
