I just purchased the new pstwo slimline edition. I would like to mod it. I have done alot of research and have came under the impression the safest mod is to replace the fliptop lid with the new fliptop lid and use SwapMagic 3.3 discs. Couple questions. Is this the safest mod to do? Where is the best place/cheapest to purchase the new lid and discs? Thank you for your help.
