Where are you moving from? Define crazy expensive? Do you have kids?
I live in north Dallas (actual Dallas city limits), but just south of Plano, and I'm in Plano schools (have 2 kids of my own). This part of town and west Plano can get crazy expensive, compared to what it use to be. But, tons of people are moving to north Dallas, Plano, Frisco, etc from the coasts where housing really is crazy expensive, and this area is probably a bargain for them. I think I saw the other day that the west Plano zip codes median home prices are now over 300K on the low end and push well over 400K at the higher end. That's median, but you would be hard pressed to find hardly anything under 300K. You won't find 2 bedroom homes, so your most likely bet is to rent, if that is what you want. Condo's tend to be sparse in this part of town, but some areas you can find them would be Addison or around the Shops at Legacy (far north west Plano, almost Frisco). Most of the schools in this area are fairly solid, although the older parts of east Plano, not so much.
Lastly, Love Field airport is pretty easy to get to from this side of town. It's a straight shot down the north Dallas tollway. Yes, traffic can really suck on there (actually it sucks every where around here now, this coming from someone who lived a few years in Los Angeles and knows what really traffic is like), but they are in the process of expanding a lot of it to help with the traffic congestion.
