Is Houston as bad as I am reading about?

We are thinking of moving here from Missouri. I need to know some places that are nice, yet affordable. I need good school districts, because I have 2 sons on an I.E.P. ( special eduction) .. Also our credit is not good, but our rental credit is perfect. We have 6 children which 3 of will probably be going to a community college, so we need at least a 3 or 4 bedroom with a basement. We are wanting to stay under approx 1200.00 a month. Also could you tell me if Houston is as humid as the internet is saying? I am from Missouri that is very sticky most of the summer. But the internet is scaring us from moving there by saying how horrible it is. And that the schools are worst in the nation, and that Texas has some work law, that makes the employers treat workers like crap, with no breaks ect... is this true>> Any info would be awesome please. Please honest in your reply good or bad, this is a very huge and expensive move for us that we want to do if it is worth it.. Thanks, Michelle
