Yea, I'm considering getting a stand too, but I honestly think I need to find a nice stool to plan the entire workbench around lol. My bench will be around 61" wide and 30" deep, which is much deeper than it needs to be, it'll offer me lots of bench top storage. I might even build a "hutch" style top to add some shelves too. Need to figure out where I'll be mounting my digital scale though, I know it needs to be mounted on a different surface than the work bench so its more stable, but I don't want it too close to the wall that its hard to see the display. I've currently got it sitting on the countertop in my laundry room, but its a few inches from the wall and kind of a pain to work with.
Yea, I thought of the storing too much crap on top aspect, but since I really don't have any other place that I can easily have a clear workspace to work on guns etc, I end up cleaning my rifles on the kitchen table and my Fiancee hates that (even though I put down towels).
I've also heard that you shouldn't put fluorescent lights above the workbench, because they emit too much electrical noise/interference that can screw with the accuracy of digital scales. Not sure how much truth there is to that, but it'd be pretty easy to test with a set of calibration weights.
