I have ProdiscF01 rebadged as Memorex DVD-R 8X.
Quality scans on my drives are OK (low 80's) vs high 90s for TY and MCC.
In my opinion, I would use Prodisc if it were cheap and my backup wasn't critical. For example, I would backup a movie I owned, keep the original somewhere else and let the kids tear up the copy.
The purchase price of my Prodisc01 was 19.99 for 50, which is the same price I can get Fuji rebadged TY for. Needless to say, I won't be buying more Prodisc.
When I originally bought them I didn't know better.
