The key is really knowing when to buy a quality tool (ratchets) and when you can 'skimp' a bit, like having a nice selection of cheap screw drivers in addition to a few good ones. It's fairly easy to over spend. But for the home guy, that is usually not worth it. It all depends on what you are trying to do and how often you are going to do it.
This is a great home tool box btw. Good price, reasonably priced, decent size.
