Not as bad as your problem, but still a PITA. I have put in several new
valves and floats of different types, several different types of flappers,
resurfaced the seat for the flapper with some 600 grit sandpaper and a
sanding block, checked to make sure everything is tight, took the thing
apart and put in all new sealants, and still it leaks. I was talking to a
neighbor not too long ago and he told me that he had the same problem with
one of his toilets (oddly enough, he had the same model house and it was the
toilet in the same location in his house). He replaced the toilet and no
more problem.

I have a Briggs toilet whose flapper started leaking. The replacement
flappers available at the home stores all leaked, too. I looked closely
at the original and it was different in important ways; I had to trim
parts off the replacement flapper to make it actually fit properly.
Could NOT find a Briggs part; some of the home stores carried Briggs
toilets, but no parts for them.
