If you only need a few discs, the price is fair, but you can commonly find better prices than this in 50 packs and 100 packs. These come out to almost $17 per 100, nothing out of the oridinary.
Memorex CD-Rs I've used were ok, made in Taiwan I'm guessing they could be CMC or Prodisc(?). CD-Rs are pretty hard to screw up IMO, but some people swear by only TY or Ritek for CD-Rs.
Best Buy has some 50 packs of Dynex for $6.99, a little cheaper. Don't get too caught up in brand names, there's a very good chance they are using the same media.http://www.bestbuy.com/site/olspage.jsp?skuId=7069931&type=product&id=1108126236666
