Well meryl, thanks for the help. Amazon wasn't of any help, but the other two have some titles. Too bad I think they're a bit too expensive". I mean... 45$ for a single DVD maybe isn't much, but when you have to buy 9 or 10 to get the whole series ....
I wasn't looking for only one series. I had several in mind, mostly stuff I used to watch when I was a kid. I guess it'll be a lot easier and cheaper for now to keep on buying manga of these series instead of getting DVDs. If I ever win a lottery, I'll think about spending 500+$ for some anime series
