Which media is best?

[ceequeue]

Have searched the forums and seem to come across a bit of a difference of opinion with regards to what media you should use for backups.

I am in the UK and, unless there are any better, was thinking of using http://www.blankdiscshop.co.uk to get my media.

With that in mind, which CD-R's should I get and should I be getting DVD-R or +R's? I have a Sony DRU-500A and have just got a Messiah chip fitted to my PS2.

Thanks in advance,

Neil.
