You might also consider north of the AFB, like up into Lewiston area and the towns by it ( depends on how suburban you want to be). The area by the AFB is close to big Factory Outlet Malls -- it it on the far edge of the city; actually in Wheatfield, I beleive, not Niagara Falls. Might be a NF zip; I have friends who built in Wheatfield about 4 miles from the area and are NF zip. Pendleton is another option. So is N. Tonawanda.The city of NF is pretty bad.
Here is a map of the area.
