I've read on a few sites that the DVDs they're selling are complete garbage. Many people that have bought them are ending up with many pretty coasters to have around the house. I was considering them myself, but went with the Ritek deal on Newegg for +Rs at $35 w/$10 mail-in rebate. The price isn't as good, but I've been through a 100 spindle of Riteks without a single bad disk, so it was a better deal for me.
Might be worth the risk with that price though...who knows? :]
