I got my copy of One Piece: Season 1 - First Voyage from RightStuf today and I really enjoyed it! I give my props to Funi for staying true to the show with their dub... and the only real thing I can ding them for is putting too many episodes on one disc; during some of the action scenes, I could see lines and other stuff around the characters as they moved.
A great start to redeeming a great show!
I recommend this and hope that they use three discs for the second half of season one.
