Though it's been in a few diffferent buildings over the years, I'm still using my ancient gray Glob-Wernicke metal office desk. Back when I first started out it was my mom's, but she let me have it when she got a newer desk a few years back.
Now, I also have the desk she replaced the G-W with, and do some work using that one (it's upstairs- Led Hornet was born on that one), but the G-W stays downstairs because even empty it weighs about as much as a Volkswagen, and it is still my main workbench.
