They are brilliant. Not as good as the creative gigaworks for £100. But for £45, you will not find a better 2.1 set, or any set for that matter.
They are far better than the two creative ones you are considering.
I bought them for my cousin, who was also on a budget, and I was pleasantly surprised by the loud, clear quality of the sound.
If you like bass, you will like them, however, if you dont like loud bass, then forget it.
