The quality of the fit depends more on the skill and judgement of the the person doing it than the equipment used. My wife bought a high end bike and got fit by the store owner using eyeball, tape measure and finally by watching her ride around the parking lot. She later got a $300 Retul fit with 3D motion capture and all the bells and whistles. All the metrics fell right in line with the norms and they didn't change a thing.
