That's a tough range to find "low cost" parts for.  For your 
application, what does "low cost" translate to?

I have been using SDX005IND4 from Sensym but it's
	a) 5" water column
	and
	b) $52 in 100's @ Digikey

Low range air pressure sensors tend to have very poor temperature drift 
specs although this can be improved on with characterizing in an oven.
