I can vouch for the Intel 82077 chip.  It really is a floppy
controller on one chip and requires very little glue to make it work.
 
The software is made much easier since it supports multi-sector
transfers and implied seeks.  You can tuirn off the 765-style polling
of drives with a command.  Formatting is simpler than the old WD
chips: you make a buffer with 4 bytes per sector instead of hundreds
and the chip does the rest.
