There's been a few times when i questioned myself and making beats. It ain't eay, that's why some people don't stick wit it, but the harder you work the better you'll be. I need to post that on my wall :).
Yeah and if you really take the time and look through FL 5 you'll find some nice sounds, most if not all are user editable. And like spindoc said find the right VST and you'll be straight.
