I still get a couple of thousand every month from my TSR projects, mainly http://www.watermark-image.com but some of the other TSR products are getting some traction.

The TSR LAN messenger has been getting some traction because people are scared of the privacy concerns with public chat clients. http://tsr-soft.com/products/lan-messenger/

The TSR photo manager gets a purchase every know and then, but to be honest I don't promote it much. http://tsr-soft.com/products/photo-manager/

All income frome those TSR projects is funneled into a new SaaS project http://timeblock.com

(My main income is from my consulting business.)
