My bench doesn't have one. I think you have to decide what your workflow is like and how a tray may help or hinder what you're doing, personally. For me, if I were someone that always put things away in their proper place, I think a tool tray would be useful. However, I'm afraid if I had a tray on my bench, it would be another place to capture dust and I'd put tools in there that probably didn't belong and then scratch my head looking for them a week later. But that's just me, everyone is different. I would need to be pretty disciplined (compared to how I work today) to make good use of a tool tray. For me, if a tool is out and in plain sight, I'm more apt to put it away.
