I doubt there are lower priced FG doors. I found all in So Cal to be the same--Masonite, Thermatru, etc.
The door, depending on style, is $280 to 350. Labor is about $500 +/-. You can easily compare labor to HD or Lowe's just call them up ask for Millworks and install fee for a single entry door. They are 1/3 to 1/2 add'l for labor over an independent guy.
