Garritan kinda sucks.
EWQL can be good, not so much if you don't want the wet concert hall sound. Also, iLok, inefficient sample player, possibly shitty customer service. Definitely some serious issues to weigh. The big point in this one's favor is the concert hall ambiance, if that is important to you.
Philharmonik is old, but better than Garritan I think. No dongle, and if you wait 6 months tops you're almost guaranteed IK Multimedia will put it on sale.
Vienna SE is a dry sound, I definitely like the woodwinds. Brass might be kind of wimpy. You can buy it in pieces tho. E-licenser is slightly less annoying than iLok. Pretty much never on sale, so you can buy it whenever.
Kirk Hunter Diamond. Kontakt library, no dongle. Definitely a point in its favor. I'm a big fan of his Concert Brass and Concert Strings. No experience with this one though. May be worth a look? Website is kind of horrendous.
Spitfire Albion... no experience with it myself but it's a newer library. Not sure if it has the traditional setup though?
ProjectSAM Symphobia... uh, really expensive. Not sure it has a traditional setup, I think it relies more on group patches. Sounds pretty good tho.
And then there's Kontakt itself, comes with a moderate palette of orchestral stuff. No section woodwinds, and solo woodwinds lack vibrato. It's all derived from VSL though, so it's pretty decent. Could be an investment rather than your be all and end all orchestral solution.
Not aware of any other full orchestral packages in your price range. I'd give the demos of each a listen, weigh the opinions people have given.
