Sstaurus,
The thing about such a question, is that everyone will tell you that the headset that they have is the best. Very few people will recommond a headset that a friend has, over their own. Very few people will critise their own. In reality, most people have only used 2 or 3 different headsets, and as a result don't have a lot to compair between.
I'll refrain from recommonding my own headset (which I too think is brilliant). But what I will say is this. Don't buy a cheap one thinking you'll buy a more expensive one when you get your licence. That is a waste of money. Buy the best that you can afford. A good quality headset should last you a very long time (assuming you don't abuse it), and should protect your hearing. Once you've damaged your hearing, that's it....no getting it back.
A good headset will also allow you to hear ATC more clearly making your training easier and quicker (thus saving you money), and make your flying more enjoyable.
Ask to borrow some from any friends you know, or to swap with your instructor for the lesson, to get an idea of different types.
