I bought some 100-pack 90/99min (90min @ 2x/99min @ 1x) CD's while back on eBay. They were very cheap (just ran out of some after 4 months with them), but did their job. I would always get write errors, but the eBayer who sold them to me, said to get maximum space, I'd have to burn at 1x, or 2x MAXIMUM. It kinda sucked writing at 1x, but he was right. I got them up to ~830-835mb. I could never write to the outer limits, but hey, it aint so bad.
