Personaly i wouldnt recommend the external mod due to amount of problems they cause with booting, especially with multi disk games but each to there own!

I hav'nt had any experience with the PS-X-CHANGE disk but i would have thought this to be a far more reliable way to have successful gameplay. Although your backups will still need patching where a protection exists.

I would personaly recommend an internal mod chip either stealth or normal, these give far better results when installed correctly, but the downside is you would loose any warranty left on the unit!
