If you're wondering where to get anime on DVD,
Amazon.com and
Barnesandnoble.com are your best bets, aside from possibly ordering directly from the licensing companies.
Also, something to take note of:
The UK (and pretty much the rest of the world) uses a different television standard than the U.S. and Japan. It also uses a different DVD region. You should make sure that your DVD player is capable of playing Region 1 NTSC discs, or get a region-free DVD player (
NOT region-free DVDs; those are bootlegs 99% of the time). If the particular series is only available in America, importing it is the only option. I'm sure it's probably not as consuming as importing from Japan (oi!), but be prepared to pay a bit more.
Not to mention that the American releases almost always have better image quality than European releases, due to the lack of effort European distributors seem to put into their DVDs (I've seen the screenshots; it's pretty nasty). If you're really shooting for quality though, the Japanese discs undoubtedly have the best quality, but don't come with English subtitle or dub tracks, so those are pretty much only an option for aesthetic reasons.
Anyway, my suggestions for series to watch:
Oh My Goddess! (mini-series) / Ah! My Goddess (movie, TV shorts, TV show) (this goes under two different titles because different companies licensed them)
Ranma ½
Love Hina (I prefer the manga - comic books/graphic novels - to the anime series, but the series is pretty good, too)
Robotech/Macross (one of the classic series; several Macross sequels have been made over the past nearly 25 years; Robotech was the way it aired in America during the mid-80s, melded together with two other unrelated series to form one long saga - Macross, Southern Cross, and Genesis Climber Mospeada are the individual series - and diverged quite a bit from the original plots, but it's still solid entertainment)
Please/Onegai Teacher (this is a more mature series, but very good, even if some of the dialog is kind of lame; this series is a love-it or hate-it kind of deal)
Neon Genesis Evangelion (confusing, psychological, and all-around psychotic; some elements might offend, but if you think about the plot devices as flavoring instead of having a deeper meaning, it should be ok; the image in my signature is from Eva, as the title of the series usually appears in shorthand)
