Buying a DVD-R Burner for PS2.

[Infernus]

I have a Messiah chip in my PS2 and in the process of buying a DVD-R / DVD+RW Burner.

I am looking at buying a Pioneer A04 burner.
1. Can anyone recommend this Burner ?

2. Can you make Iso's of original games and burn them back as is?

3. Do you get patches / Copy guides for Ps2 Original DVD Games?

4. Can you only burn back DVD games that was patched by official groups ?
