Westerville is my first choice. I grew up here, and when we moved back I wanted specifically to come back for the kids. Look around Blendon Township. Westerville schools, w/o their income taxes. Galena and Sunbury were high on the list too. There are a number of houses back in Sunbury Woods for sale right now that are great deals. Mature neighborhood, a few parks, pretty quiet, and younger families moving in, school right in the middle.
Being by Sunbury Rd,161, and 270 (literally my back yard) gives great access to anywhere in Columbus within minutes. And you hear if its a "busy night" or not. Easton is 3 miles away, Dublin is 10ish. I work in Gahanna, and the wife works near Bethel and Sawmill takes us 10-15 minutes to get to work.
