@bson, From front to back what is the depth of you workbench? It looks like maybe 40 inches or so? Also, it looks like you've got a Rigol DP832 on the left. Is the back of the Rigol flush with the back of the bench or does it overhang some?
Apologies for the very late response! I totally missed your post. The bench is a heavy-duty 72x36" with a laminate top and an ESD mat. It's this one here:

The top also has a foil underside, which is also grounded. I then added a 72" shelf, also steel, and also grounded. It has power outlet cutouts on the front, but I haven't populated those since I really no use for power cable hanging down onto the work area, instead I attached a couple of long 60-70" power strips along the back.
The DP832 and all other instruments protrude a little on the back, but all feet are on the top.
The deepest instrument is the HP 3577A VNA, and it sits on the S-param test set which sits on a ~1" wooden box under it. This guy protrudes well into the back, but not badly or dangerously so. I keep the bench a bit off the back wall for this reason and to make it realistically possible to get in and move a GPIB cable or something. It's also too heavy with so many instruments (especially the VNA) to slide much. So I try to keep the rear accessible to begin with.
The next item up is likely an Agilent 8753D VNA...
I'm asking because I want to add a new bench to my limited workspace but am having a hard time deciding on what size to get.
Yeah, I wish I had responded sooner! It's GREAT to have a deep bench. This thing is also rock solid; I could stand and jump on it and it couldn't care less. The top is along the lines of 1.5" thick.
Very heavy, but very easy to assemble and since it has bolt holes also very easy to ground.
I also attached a wrist strap connector on the bottom of the top.
