Prodiscs are decent to very good depending on the brand. They are also inexpensive compared to other media without skimping on quality - although there are much higher quality CD-Rs that are also priced accordingly. I like them, and other forum members simply adore them.
I've seen Silver/Silver discs (even DVDs) but I generally don't like them as much as matte finishes or inkject printables - lines to write on are my thing (or a surface to print on) and greasy hands handling it easily make the top of the disc lackluster. Nevertheless, Prodisc CD-Rs are generally ok.
Do you have any scans of it?
