Before I Forget…

Maybe someone who reads this site can help me with this. I'm looking for a place, preferably online, to buy two-sided blank DVD-r discs. I don't mean dual-layer. I mean the kind where you can burn Part One of a movie to one side of the disc, then flip it over and burn Part Two on the other side. Most companies have stopped making or carrying these because they're quite unreliable. I know this but I have a need for them in spite of it. I'd like 16X but will settle for whatever I can get.

Also: I'm looking into maybe/possibly/I'm not sure getting a wireless Internet card for my laptop. Several cellular companies offer them and I'm wondering if anyone reading this has a strong recommendation or warning about any particular provider or plan. Natch, I'm most interested in hearing from anyone in Southern California, which is where I can usually be found. So far, the deals I've seen all require that you to sign up for a couple of decades. Having once gotten stuck in a long-term analog cell phone plan when the rest of mankind went digital, I'm a bit leery of committing to anything that may not be what I want after the next Consumer Electronics Show. Anyone have a suggestion?
