All towns west of Irvington are good. Maplewood(Part by the trains station and to the west of it is best), Millburn, Chatam, Summit, Madison, Springfield. All have good schools. Millburn/Shot Hills is best if you can afford it( for 1/3 of an acre its $1MM and up for something decent). Just go on any real estate site like Zillow - Real Estate, Homes for Sale, Home Prices & Values
, plug in your minimum and maximum and go from there.
