For $30... Really?

I don't think there's anything wrong with ask people to pay upfront if you have good demos, videos and screenshots.

Numbers showing that freemium increase conversion would be interesting, I just do see it being worth the hassle.

Also, it's PHP, how would you avoid people just using your code and not pay? You could do a stripped down version, but that's a lot of addition work for $30... and can you strip out that much functionality from something as small as this?
