Thriller,
There should be plenty of nice neighborhoods in Broomfield. The mountain views are better in Broomfield than down south, but I still like south much better.
Have you guys checked out both Broomfield and Lone Tree/Highlands Ranch? If not, I'd recommend spending 1-2 hours in each area. As far as down south, take 25 to Lincoln (1 exit South of 470), go West about 1.5 miles to Lone Tree Parkway, take a right to drive past Lone Tree Golf Club, swimming pool, and library. Take a right at the first light (Yosemite), take it back to Lincoln, take Lincoln for about 5 miles (it becomes University) to get to 470, and take 470E for 4-5 minutes to get back to 25. Stop and check out a couple more neighborhoods if you see some areas you like.
