Robotech is for me the first animated serie that came from Japan. All episodes where (are) in English (in the original version not of course). I was so possessed by it that I recorded the sound from almost every episode on cassette tapes.
After many years, I discovered that I could buy a few episodes on video. Sofar, I have 1 to 7. The tapes are not cheap, and consume a lot of space in my already crowded room. But it is my goal to have them all once. I have found a very good page with more information here.

I have some screenshots for you below.
