Here are some DVD versions from Anime-Kissaten

As far as I know, they did the best releases, but from what I remember from when I watched the TV, the video quality and audio were not that great, but it was fine... It should get better as the episodes progress...

If not just bear with it, once you get to the OVAs the qualty improves exponentially...
