Software stuff

I have a scanner at home. (I believe it's classified as a 'flatbed scanner' but I don't know all that much about it.) For those of you with scanners, what sort of scanner software do you use? I usually use the wizard that pops up when I plug the thing in and I was wondering if there was something a bit more....efficient. But I don't want to spend a ton of money on it either. The wizard is free and it works. If there isn't anything free (or at least really cheap) that works better, then I'll just deal with this.
