I believe so: you need an omni and two figure-of-eights for a minimal setup if
I remember. The 8s are places front-back and left-right in the horizontal plane,
and coincident with the omni. Of course, depends what you mean by cheap (most
cheap mics are Cardiod, aren't they.)
But you'd better listen to Richard or read the web page on this one: I've
forgotten all I ever knew about ambisonics...
