Query: One of the best DBZ DVDs

This was one of the first Dragonball Z DVDs I bought, and I was very impressed. The Androids Saga climaxes here, when Trunks, Vegeta, Krillin, Piccolo, and Tien discover Dr. Gero's lab. Goku, who fell ill in previous episodes, was taken back home by Yamcha. Dr. Gero activates Androids 17 and 18, who proceed to kill Gero and activate the giant Android 16. The Androids fly off to a mountainside roadway, where Vegata challenges Android 18 to a fight and gets a little more than he bargoned for...Everything about this DVD is great. The sound quality and picture image are very good, and the episodes are 3 of the best in the series. Of course, it's best to see the earlier Android Saga episodes, but then watch this DVD. It's very entertaining.
