We live in the Plano/Allen area. I have an Allen address and we are Plano schools.
We love this area. We've been here (in the same 3 mile area) since 1989. Our daughter will be 16 in December and is going through the Plano schools which are excellent. She has been challenged wonderfully through her education, she's now in 10th grade, all honors student, orchestra, cheer captian. We feel she is getting a good, well rounded education.
I've also been a substitute teacher at the same elementary school (exemplary and Blue Ribbon, many honors) for 10 yrs. I'd say there are 18-20 children per classroom and teacher aide readily available and around a lot.
The Allen schools are also very good. Allen is growing rapidly and I think the tax base for schools is a bit higher than Plano but Allen does have good schools as well.
As for neighborhood, our neighborhood is full of wonderful families. We have families from all walks of life here.. Many corporate executives, SAHM, WAHM, lot of children out playing. It is common to be outside on a beautiful evening or morning and see a group of people just hanging out, talking while children are at play.
Our street is very low traffic, we live on a large lot backing up to a large 85 acre wooded area that is Park and won't be developed. We love our privacy (can't look out one window and see in the neighbors window). We can be out back and no one see us :) We love the wildlife (bobcats, owls, etc). Of course, you are careful but we love this area.
If you are interested, let me know and I will PM the neighborhood website to you. As for price ranges, our area is around $300,000 -appx 1M -- of course, depending on the location and size of lot/home.
If you come here, I think you would love it. Many things to do, DFW is a great home airport with easy access to go anywhere. LOVE Field is great for all the short trips.
I've not personally experienced the ultra conservativeness I've read about in other posts in my area. We are quite open minded (moreso than many). Our specific area is more white collar area than blue collar areas. Most moms in our neighborhood are SAHM and active volunteers in the schools and city.
Best wishes on making the best choice for your family.
