Wylie/Sachse/Allen are nice areas, but may be a bit of a drive. My in-laws live in Corinth and love it. DH works in N. Dallas and we live in Keller - commute is 45 min - 1 hr each way; they are doing construction on the freeways from Dallas to Keller area and traffic is a nightmare, construction will be ongoing for a couple years.
If you haven't found this website yet I highly recommend www.dallasareamoms.com - you can get a TON of info from moms in the metroplex, plus it's just a great site to connect with people.
