I got the VO from the actor and I must say it's quite good although I believe I have done a decent job myself so I'm not at the moment sure which one I should go for.
Perhaps you can help me make a decision.
I will upload one line delivered by myself and one by the actor so you all get to chime in and tell me about your preference.
UPDATE: Here it is.
I do have a cold and don't have a good mic or anything remotely professional so the audio quality's difference is noticeable. But it's just an initial test.
I think the actor did a very good job. My only concern was that I didn't hear much pain in his voice as you'd expect from a tortured prisoner.

I don't have KoToR installed at the moment, so can't tell how these VO will work ingame with ambient music. It isn't simple choice as both lines have their own flavor. I would choose Actor's VO purely because of 'cleaner' audio quality.
I decided to go with the service of a professional actor to record the lines of the Mandalorian Prisoner.
He will be the only one that is going to have a new voice.
