Carpenter for 15 years and ops manager for a cabinet company for the last 6 where I oversaw anywhere from 1000-1500 installs a year. Lowes and HD both sell the exact same name brand lines as every big local cabinet company in the area with the only difference being the local places get a couple extra finish options and door styles.

Never said there aren't good installers. I'm saying the local cabinet companies don't use any of the good ones. To get a decent install you'd have to find a decent designer, installer, and play GC yourself because you're not going to get that as a package for a single remodel.
