Any orchestral composing type Reaper users tried the Synful Orchestra free 15 day demo? It's unclear on the site whether you can re-install the demo after the 15 days expires, but they say it allows installation if you have already installed previous demos. It sounds interesting - MP3 demos on the site seem remarkable considering this is not a sampled library, but a synthesiser that produces pretty realistic sounds and articulations from playing styles.

It's about £245uk to purchase, but I guess if you can produce something in 15 days or less, it qualifies for this thread on free plugins (check if the demo license covers commercial use if needed, of course).It's at
