I've recently picked up Nordstrom brand 'trim fit' shirts from The Rack at $20/shirt. You can't find a better fitting shirt for this price. The waste suppression on the shirts is very good...they fit me like a glove. I'm 5' 10" and 160 lbs and wear the 15 32/33.
I also found Nordstrom Trim Fit to fit me really well. For the price they seemed pretty well built as well. Styles are limited at Nordstrom Rack, but they seem to get new styles/colors in every now and then.
