As far as I know, the R03s are just as good as the Ricohs, and they burn at 8X instead of 4 on most drives.
I bought about 400 of these Ritek DVD+Rs as well as about 100 of the -Rs so I've burned both Ricohs and R03s. No coaster so far (atleast not any from the media's fault).
I would have bought some more but I still have about 200 of these Riteks (both + and -) and I just bought another 250 of the TDK ones that were on sale for $10 (25-pack).
This is a good deal if you guys are in need of some new blank DVDs. However, DVD-/+ Rs are dropping in prices recently (probably due to dual-layer discs) so that would make this an OK deal instead of a hot deal.
