DALLAS CNA schools?

I've found information on lots of them, and I was wondering if anyone had a particular recommendation for any CNA schools in the Dallas Area. All the other sources I read seemed to be written by the people who worked for the school and I'd rather an unbiased opinion (or as near coming to it as i can get, lol)
I have found wildly varying prices, from $160 for the class to $1,000, and I am just not sure where to go! Money is a huge object because I am borrowing the money for CNA school from a family member and I would prefer not to borrow more than $500... Dallas Area (esp. the east side) schools preferred but any opinions welcome.

Thank you in advance
