Replying to Video editing that won't break the bank

I've started to edit a little bit and i enjoy it and i want to get better.  I'm stuck with WMM which works alright but there is no variety in efffects and the color variations are muy homo.  I used the search bar and people were asking the same question.  Avi and premiere cost a little more than I can afford at the moment.  I'm asking whether anyone knows of any video editing softwares that are somewhere between WMM and the crazy expensive programs.  Any help would be cool.
