Well the best version to get with "great" or "perfect" translation would be the Animeigo set. Then you're looking at $65.00 per box set. Each box set has 3 DVDs and there are a total of 9 DVDs. You can them here at Twin Moons Anime:

Otherwise, if you don't want to spend too much, the bootlegs that Kevin carries are the next best thing.
