I'm biased (as is everyone, I suppose), but I think the Chandler, Gilbert, East Mesa areas are terrific. Mostly Gilbert, to be honest. It's a relatively new area, but there has been a lot of interest from business interests, which means jobs, additional tax revenue to the City (which means better services, better schools, etc.), and great schools. Prices are stabilizing now, a little earlier than other areas in the Valley, and I think the area is poised for a good recovery.
If I can be of any assistance, let me know.
