I know a selection of sites that allow free/cheap downloads of VST instruments. However, usually, it's a case of trawling through a shitload of pictures and descriptions, without much idea what they will sound like. I have downloaded quite a few, with hit and miss results.

Does anyone have any specific recommendations for decent quality free/cheap VST instruments? Also, does anyone know if there are any free sampled piano or strings VST's? I have the free bluenoise drum kit, and it sounds amazing to say it's free.
There is poetry in despair.
