I rarely burn anything to a CD that I don't plan on keeping for the long haul, so single burn disks work just fine for me.

Same here, and that's why my CDRW stayed in a drawer for so long. But I was talking about DVDRW media. I do a large amount of DVD video burning (concert videos, downloaded TV shows that I want to watch on large screen, ripped Tivo shows, home videos), and burning a one-off TV show I downloaded (I wanted to watch the HD rip of Tru Calling I downloaded on the new widescreen TV) onto a write-once DVD makes no sense.

And I tend to purchase them when rebates are available, so I rarely pay $1 per disk.

Ditto. The Office Depot across the street from my office was moving and had a 50% off sale. I bought two 700MB 100CD spindles for about $20 each. I've been living on those since. But until recently, you couldn't get DVDRs for under $1 each, and that's what I was talking about. Thankfully Rob found a good deal, though I still won't be using them for short-term storage.
