Query: New Models Lack Strength of Old Ones

I have an old Workmate (10 years old) that has been pretty good. It has a couple parks that have worn out, such as the mechanism that holds it in it's compact form when not in use, but over all it have been a great tool.My in-laws gave me a new one last Christmas and it was much more flimsy and was even missing parts out of the box. My wife called Black and Decker and they said it commonly happens and we should reveive the pieces we need within a few weeks. Well, it's June and still no parts. Granted, I should have followed up with them by now. Even with all the parts, the units are much less sturdy now than a few years ago. Back then their usability justified their cost. Now, that is simply not the case.
