Given the DVD's are going for £26+ on Amazon and the last time I looked on iTunes it was going for over £35, £14.99 isn't a bad deal if you don't mind Apple and iTunes.
I don't care what anyone says but this was one of the best cartoon series EVER and an important part of growing up in the 1980's. Don't miss it if you can help it.
In the year 1532, a Spanish orphan named Esteban joins a party of Spaniards in their search for one of The Seven Cities of Gold in the New World, hoping to find his father.
