How to learn to play drums?

I'm thinking about learning to play drums for some time now and I have a question. If I'm a complete beginner should I still get a full drum set? I know you can buy a cheap electric set for like $300 but can I start with something smaller and simpler? Are there some kind of electric pads that would work for taking first steps and that would later let me progress to full drum set? It's not that I don't have space, I'm just not sure I will stick with it and I don't want to be stack a big set I don't use later. Or full set is actually the best way to start?
