What's a good DAW that has LOTS of instruments?

I just need a good daw (pc only please) that has lots of instruments. I am mostly looking to make some techno, trance, etc. I also have a casio keyboard, so MIDI functionality is a good thing too. I tried FL, but I felt it didn't have enough instruments, and I don't know how to add them or which ones to add... so. Thanks for your help.
