I've personally never had any compatability issues with the crap cd-rs that i've bought (usually either decent/good factory cyanine or no-name factory pthalocyanines).
i'm concerned with longevity, in spite of the fact that i might be switching media formats within a few years, but I want to be able to archive my stuff at least 20 years... cause i dont want to go through the process of copying stuff from old media to new media all the time.. i have better things to do. for example, nearly 95% of the stuff i had on floppies from years ago are still on floppies. you think i'm concerned about their longevity now? you bet. i'm gonna transfer them to cd eventually, but for the time being i just hope they last.
another thing is durability. oftentimes with the cheap generic cd-rs you get either a cheap laqcuer/topcoat, or no laqcuer/topcoat at all (these are the ones where both sides of the cd looks almost the same). The problem with this is that if you tend to be hard on your cds, the topcoat can tear and flake, and when that happens, your cd becomes unreadable. discs like kodak have a strong protective lacquer that is in addition to its reflective layer, and they hold up much better under adverse conditions. case in point, I leave unprotected audio cds out on my dashboard so i can grab em easily, and the cds without protective coatings start to flake VERY easily. but it doesnt happen with better cd-rs.
yes, you get what you pay for, and $140 for 200 Kodaks is a very good deal.
