Dinsmore makes analog and digital compass sensors (and modules) based
on hall effect devices. Basically, they have a damped or undamped 
rotating magnet with two hall effect devices to sense its position
assembled into a small case (1/2" diameter). For $35 (quantity 1) you 
get analog output, $10 or $15 (quantity 1) gives you 1-of-8 digital
output.

By the way, they have a new analog sensor using different hall effect
devices that provides about twice the output of the old sensor.
The part number is the same as the old with an "A" appended.
(Off the top of my head I think it's 1526A, but don't quote me.)

It's not flux gate technology and it's not a "chip", it's an assembly.

They aim for the automotive market.
