Woodbridge has a huge range of prices from 150k - 500k, mostly resale on the west side of 78 and new on the east of 78 off Ranch Rd.

The elementary school in Woodbridge, Cox, is new, about 3 years old. I was impressed with the technology there, with projectors in every classroom and the kids put together a "tv show" for the morning news. Over on the new side, off Ranch Rd, they are building a brand new elementary school to be open next year. The only downside is there's a radar tower that's not so pretty right by Ranch & 78.
From Woodbridge you'd have a 12-15 minute commute taking the back roads with little traffic. I work at Cisco over in Bldg 4, and it's a breeze to get there. My wife is jealous

Oh, and most of the area already has FIOS service... so for telecommuting, it's a nice plus.
