Did I get ripped off? Also, bad lasers, wrong media and strange modchips!

[Farkad]

Would it be safe to use lower quality discs(Memorex) once the Romeo Mod is done?

You see, I'm still extemely paranoid of the PS2 making the slightest noise. I just turn it off after 15m of use.
Someone please ease my mind!

As for better media, I don't have access to it. Memorex is the best I can do, and a post in these forums checking DVDs said that Memorex and Riltek are just as good as originals.
