It is already a lot cheaper than other similar tools (but less mature also). Any cheaper and it might start not to look credible. And I anticipate that some users might need quite a lot of support, so I can't afford to make it too cheap. If it is only worth $25 to you, then you aren't really my target market. I went for time limited, rather than use or feature limited, because it allows people to test the full capabilities. The 7 days use don't have to be contiguous.
