I bought the Kingston CDR's last week from Outpost...Specs. - 80min, 700MB, Multi-speed 8x. They are blue on the bottom....SuperDave you may need to have your burner looked at....I haven't had a coaster yet...They are great! I usually use Verbatim, but I may have found a new brand. I bought the 50 pack for like 20 bucks. Very good price and worth every penny. I wasn't sure how they would be, but I think they are great...Hope this helps someone out with doubts about Kingston.
