Your cart set-up is great for a portable workspace. If you have the flexability to set up a workspace like sunder is running, better. I think you are more interested in something a little more mobile so that you can tote your gear around when you need to. This works well when you have a truck or trailer to mount it all to, but not so well when you are trying to do a compact deal for fitting in a smaller shop.
