Refunds & Lean Code

Hi There

I am considering Themeframe after trying out Headway (couldn't get my head around it) and I have two questions:

1. Do you offer a cooling-off period for a refund? Some themes give you 30days to tryout and give you a refund if you don't like the theme.
2. Is the code leaner than Atahualpa's generated code. I ask this because I built a site with Atahualpa and the custom CSS ads a tonne of code that the site takes forever to load, so much so, I am having to rebuild the site. Do you have sample sites I could look at to see how it reders the source code?

Thanks

Kay
