I've gone with the Evermotion Archmdels packs, they are very nice quality models with textures, even though you mostly have to run them around from 3ds or obj format (accutrans 3D is good program for that, it's free).
Newer evermotion archmodels packs are VERY nice, I use mostly those, it's evermotion pack 43 if I remember right (realistic plants), you can get around 50 different high polygon plant models with textures and UV maps for just around 120 USD If I remember right, so every european, order them somewhere US, Dollar / Euro is very good now!
Thanks for the comments
