I use Fruity Loops as well. It is very user-freindly and if you like it, and register the Pro version, you'll find it to be very powerful. I've had it for a few months-I started with version 1.7 and I'm now on 2.0. Every update has made significant improvements on what is a very strong program to begin with.
However, like Gidge said, the samples that come with it suck; there are much better samples to be had.
