In particular to replace EWQLSO. Not that the Kontakt library is bad, but some more articulations would be nice. Needs to be reasonably priced, I've found a few thinks that look cool but want like a grand and I just can't bring myself to spend that kind of money replacing a $500 library, particularly when said $500 library is the whole orchestra.
 
How I wish EW didn't do their Play crap and I could just get it in Kontakt format :P.

I'm truly happy with Kirk Hunter Strings.....stright out of the box, it was Wow!! There's a lot of really good libraries over at KHS.

Hmmmm. Concert Strings Whole Divisions might be doable. $250 isn't too bad. Not quite as big a string section I like (I'm a sucker for massive 70 peice numbers) but looks good overall.

This with the Kontakt brass, winds and percussion would be quite nice.

Kirk Hunter strings.  Very cool features, very nice strings/orchestra.

Another vote for Kirk Hunter.

Cinesamples Cinestrings maybe out of your price range but it's excellent value at $429
