I have begun the long and treacherous process of searching for a new SUV.  I don't necessarily mean "new" one or two years old would be okay.

I have narrowed my search to the following:  Ford Explorer, Chevy Trailblazer, GMC Envoy

What are the best websites for comparible pricing?  Also, what do you think of the choices above?  Which companies have the best incentives?

I have already used www.truecar.com and www.autotrader.com
