This is a very good offer, and the orchestra sounds really good with good quality legatos. If you have the time, check the videos on their website. But if you want an also good orchestra for free, try the Spitfire BBC Symphony Orchestra - Free Discover edition. You fill up a questionnaire, and after 14 days you receive a download for the free VST. It is a full orchestra, but with only a couple of articulations per instrument, and no legatos. But it sounds good enough for mock ups. Then you may want to upgrade to the Core edition (450 euros, but they have almost 50% promotions from time to time) that gives you dozens of articulations, and many mics.
