Hovis, no this one does not vibrate, (see post above) We've been using it for 5yrs. For your own benches I strongly recommend isolating the bench from the walking slab. To do this you must form and pour the bench first and then pour your walking slab around it keeping it from bonding to the bench. This applies if you're pouring a "light" setup. The one in the pic is "medium" weight and it's set on compacted gravel, SERIOUSLY compacted gravel. If you're doing one like this and you set it on a subgrade which has been compacted with something like a walk-around plate compacter it WILL MOVE! If you set it on 12" or more of contained ConAg that's been hammered in with a jumping jack you'll probably be OK depending on your area.
Some of the "heavy" benches we've done, (one of them is in the web gallery, the one with the 6" thick top) are extremely stable. I shot for years off of the one in the gallery and a person could dance on the table while another was shooting. (We didn't do this a LOT, but you know...fundraisers and after-hours stuff)
