I built and sell a collection of plugins for the Delphi IDE at http://www.twodesk.com. (Yes, people still use Delphi), for a consistent single-digit multiple of $1K each month.
That is AWESOME... back in 2000, I was writing a vertical app for an oil company using Object Pascal/Borland Delphi (it was still Borland... and Kylix... at that point) It got me using Interbase/Firebird/FirebirdSQL for a couple of years. Glad to hear it's still around.
I was developing primarily in Delphi for 5 years, took a year off, and now doing it on a the side again a little bit. It's not SO bad mumble mumble mumble
