Help on decision (Outlaw, sCRYed, Key,...)

[naugem]

Hi.

I'm trying to decide which anime series to buy. Based on the reviews I've read and on what is available here, I'm considering the following:

Outlaw Star
sCRYed
Key, the Metal Idol
Martian Succesor Nadesico
Samurai Deeper Kyo
Ayashi No Ceres

I'm looking for an anime that I can watch a chapter each night before I go to bed, so I don't want anything too heavy or phsychological, but I don't want anything too goofy either. A little bit of everything would be fine: plot, interesting characters, some action, some romance ...

I'm also considering Escaflowne, but that schoolgirl goes to another world thing puts me off.

Any opinions?

Thanks.
