Plano Texas Real Estate page getting updated

My Plano Texas Real Estate page is getting a new look.  I've broken out all the subdivisions I can think of into individual pages that each have keywords, titles, and descriptions (if I did it correctly).  The IDX I'm using is www.WolfNet.com.  Who do you use and why?  What price point do you feel is appropriate for an IDX?  Would love to know your answers.

I've also updated the other cities on my site.  Look also at Carrollton Texas page.  it's very similar but the links and images are all individually tagged differently.
