Thanks to PSP-Vault founder zmcnulty, we at PSP-Vault have been archiving all known PSP variations in our Guide Vault. I have expanded on zmcnulty's work to include all PSP-2000 variations that were missing and all the recently released PSP-3000 variations. I think I have included all PSP variations to date, however if you think I have left out a model please let me know in the comments of this article. You can view the Color Variations guide, containing all the known PSP variations, here.
