Cloning PS2 Games, is it that easy?

[Juiced46]

Ok im new with all of this so bare with me. I have a V7 PS2. I am looking into purchasing the Magic 3 chip. Is there any downsides to this chip?

Using a DVD-R writer can i just do a DVD to DVD copy/clone and it work? or is there more to it?

I am going to be purchasing a DVD writer within the week. Which is a good one to get for between $200-$300?

Thanks in advance
