Site plans

I have updated my search box on my site four times since the start of 2013, and I'm never entirely sure what design to go with. I currently like the design of my search box but it is so flawed that it's become such a site hinderance. Even now, as browsers get better and better, things just don't always work the way you planned with websites. 

Tomorrow evening I will begin a new search box. You can tell me what you think in the feedback form.
