One Piece MAC

[Buckets]

Anyone know what version this is a rip of or if they did their own subs like in their version of Hellsing? I really want to buy one of the One Piece sets but I'm afraid the subtitles will be so annoyingly bad that it will detract from the experience... I LOVE the few fansubs I have and I don't want bad subtitles to ruin the series for me.
