Excellent question. I've no idea how many hours I've put in it currently. If I add up the codebase of the classic version plus the under-development new version, I get to at least 150,000 lines of code (including comments and whitespace). I know LOC is a crappy metric, but it does give a sense of scope.
I haven't tracked the amount of manhours at all. Ten hours a week gives me 2000 over four years, that seems realistic (although a little low considering the amount of code). At market rate that would make the project cost about $100k but of course something is only worth what a buyer would pay.
To answer your question: I'd be a happy camper for a couple hundred each month. Enough to pay for expenses (hosting) and justify a day off from the day job. To spend on projects like this of course.
