Jason,
My observations within the company I work for (BAe146) are that the split between handflown raw data v flight director approaches is almost 50/50. Coupled approaches are only ILS. Most pilots seem to hand fly to 10,000' to try and keep their scan rate up.
IMHO, the biggest disadvantage of a flight director, is that in most cases it reduces the need for an effective instrument scan, thus self discipline is need to keeps one's scan effective.
