Getting about 60$ a month with http://udeployer.com/ - considering the amount of work I put into it I'm definitely opting for more than 60 dollars, but better than nothing... at least I can have a fancy dinner once a month :). Continuously expanding with some marketing, hoping to reach the $500/month mark someday.
Experiment with 10x the license fee just for one month. This is clearly targeting bigger teams / enterprises / SMEs rather than home users. $19 -- what were u thinking?!
Unfortunately I was selling this for about $200 and I wasn't getting any buyers at all, so I was forced to switch to a lower price.
