i would like to tell you about
EXCELL SAGA
it is a great anime, and i find it a bit interesting
TRIGUN is a mixture of american western and science fiction, with a tad of humor. as is in OUTLAW STAR, but this involves space more. lol
if you like school stuff, PEACH GIRL is a good anime
another good SCI-FI would be SOLTY REI
a good ramdom fave of mine is called MUSHI-SHI

Hmmm!! I’m getting it very well so as to what you want exactly. I am anime fan and I love anime. I recently saw a site on Internet called animemine.com. I would highly recommend you for AnimeMine. It is a largest social network especially for anime fans and artists. AnimeMine has a unique blend of functions that gives great opportunity for anime Otakus(fans) to connect and share their interests, art, and music in the anime world. You can find an array of opportunities to connect with others. It is free and simple to register and participate.
Hope this help you.
Thanks!!
