If EGR is a bit spendy, consider Wilcox Park. It's just across the EGR city line, inside Grand Rapids proper, It's a great little neighborhood near Aquinas College on one side and the Farmer's Market on the other. Wilcox Park is a perfect place to play with your kids, or walk your dog, and there's a good Catholic elementary school on Wilcox Park Drive. You can walk to everything from the Post Office to the market to the bakery. And there's 3 different bus service lines within two blocks in any direction that will take you all over town, cheap.
P.S. Once you find an area that you may want to live in, research it on the web. There is a ton of information out there for you to take advantage of.
