Wife says the living room carpet has got to go. We started looking at solid wood, laminate and engineered flooring. I don't want to install solid wood although I like that best. My back just won't take the swinging of the mallet for the pnumatic nailer. We have 500 sq. ft. to install. Anyone with experience in either of the other two choices care to share thoughts on why they chose one over the other? Thanks, Sean
