The ones you see on e-bay for that price are probably the generics or the Legacy (princo made) with no labels.... Stay away from them... They suck....
If you look on e-bay you can find the TRUE Princo's with the white labels and jewels cases for about $1.00 each...
Those work perfect in everything I have, including my home dvd player....(Also, CompUSA brand DVD-R's work perfect also. A little more expensive than the Princos... 5 for $11.99)
Most all the people in the UK use Traxdata..... They are cheap and work great... I have a couple of games on Traxdata that I got from a friend of mine in the UK (you know who you are
) They also work great....
Of course all of the BIG Brands (Verbatim, Apple, etc..) work great also...But they can be pricey....
