UC Gundam Blu-ray Libraries Mobile Suit Gundam

If you're looking for the complete Mobile Suit Gundam series, this is a great choice. Great video and audio quality. Includes all episodes (including episode 15) with dialogue and music. All the episodes are in Japanese, but English subtitles are available. If you want an English dub, this is not for you. Subtitles are done by a competent person, so it's easy to follow what's happening. This is one of the seminal series in anime and is worth watching

This has Japanese audio, and subtitles are available in Japanese, English, and four different versions of Chinese.If you want the full series instead of the movie versions, this is a great option. The box is beautiful too.
