I'm running out of books to read, so it's almost time for my annual amazon shopping spree. But I've pretty much exhausted all the sci-fi classics by now (basically, if it's Clarke, Asimov, Heinlein, Gibson, Orwell or Card, and worth a damn, I've read it, as well as several major classics by other authors), so I need some suggestions. Here are some current ideas I'm thinking about, but any suggestions are welcome:
I'm sorta feeling in a Mech kind of mood, so I'm thinking about looking into some Battletech novels. I know the universe and like both it and mechs in general, so it has some serious appeal. But I've got no idea which of the books are best, nor where to start, so if anyone here reads those, I'd like some input. As for timeline, I'm definitely looking for stories that take place pre-and-during the clan invasion, as that's by far my preferred period. One absolute requirement is that any books absolutely, positively,
must feature some kick ass Mech battles

Trilogies and the like are fine, I like long story arcs.
I've also been thinking about the Uplift series by David Brin, as the premise looks very interesting, but since it seems kind of atypical I'd also like to hear from anyone who has read those first.
Finally, and in the fantasy realm, I'm feeling rather tempted by the Books of the Swords by Fred Saberhagen, but I'm having a ***** of a time finding anything that amounts to a decent review of them. The premise looks awesome though, but I don't know his work at all and bad writing can kill even a killer premise.
Soo... if you're a Sci-Fi/Fantasy lover like me and have read any of these, please help me
