> But it's just a desktop app, just a one-time payment. In which case, consider building a feature or time limited freeware version initially, without support, offering users to buy/upgrade, and submit it to all the shareware/freeware joints out there. That should get you a decent number of potential buyers, a good percentage of which should convert. Test the waters this way and if you still don't get enough numbers, ditch the idea of full commercial version. HTH
