I'd say go with brandnames... Sony, TDK, Imitation, etc.. stuffing around with cheap discs will only save you a small amount in the end. And there is nothing more frustrating than burning something to CD only to find months later when you access it that the disc quality has deteriorated & you've lost data.
Also, here's some info to answer a question you're bound to ask later. It's a bit generalized, but still useful.
<B>How long will rewritable CD-ROMs (CD-Rs) last?</B>
The CD-R's color is a good guide to its longevity. The dye type matters most because dyes have different chemical compositions, and thus different life spans. The four major dye types used in CD-Rs can be identified by their intrinsic color:
<B>Cyanine Blue</B> - green or distinctly green - life range from 10 years to as high as 75 years.
<B>Phthalocyanine</B> - Usually gold - reputed shelf life of something like 100 years.
<B>Formazan</B> - Greenish gold - hybrid of both above.
<B>Metallized AZO</B> - Dark blue - a long shelf life, approaching that of phthalocyanine.
In other words, the ratings are as follows:
Green, Blue-Green == Standard
Greenish Gold == Good
Dark Blue == Better
Gold == Best
