My backups are mostly on
Verbatim
Panasonic (my personal fav) - Model no is rf120
And Pioneer.
All the above are expensive mind, but i have a version 4 which after a year of neo2.2 has become EXTREMLY fussy with dvdr's. So basically I work on, whatever runs perfect on the version 4 is the better disks.....Then put it on my nice new v7
Don't get me wrong though, there are a lot of cheaper disks out there. After reading from a couple of the members here i'd be curious to try traxdata dvdr and see how the v4 copes then. Just can't find anywhere with them in stock!
Hope this helps,
James
