i buy the princos from http://qtccdr.com/
not sure how good they actually are, but they work great for backing up my xbox games, which is all i burn to dvd. except for using my -rw disc for transferring large demos and mods back and forth from a friends machine. its a shame that its faster to burn a full dvd, walk over to his place and copy it to his hdd quicker than i can transfer the same thing over our wireless connection. i should really start looking at moving from b to g.
