I don't generally recommend software (people have opinions on what's better, stupid fights start, it's not pretty.)
However, there's a whole thread dedicated to free software. Some are totally free, others are just demos. If you're looking for cheap, I'd suggest going that route, at least to start.

Without going free, you're probably going to spend a few hundred bucks (at least) for something good, unless anybody knows of any good cheap software. I don't, I mostly use free stuff.
