You're other option is to become a pirate (ARRhhhhh). Here in NYC, piracy seems to be such a pandemic that they're running Ad campaigns for people to report software piracy at small businesses (https://reporting.bsa.org/r/report/add.aspx?src=us).
Here's a business model I've been thinking of that I hope developers will adopt. I call it “Entrepreneur lay-a-way”. Basically if someone is a-self described entrepreneur you give them a full 1-year license to your software for free. At the end of the 1 year you charge that users credit card for the full license plus interest. The thought being if the entrepreneur is successful, in 1 year he'll be able to afford your software with interest. The entrepreneur benefits deferring payment for a year, and can use that money for other purposes (marketing, etc). He can then utilize you're wonderful tool to create value for his users and the world. It's a win-win all around.
