If I were you I would get 'replicated' CD's rather than 'duplicated' ones. Replicated CD's are the ones where they press the information onto the disc. Duplicating them is just like doing it on your CD-R/RW drive in your computer, although I'm sure the lasers are a little better in the manufacturing process of most companies then your computer one.
$1,490. does'nt seem to much for 1,000 CD's with four page folder, tray card, jewel box, and free UPC bar code. That's if you can do your own artwork for your project.
