Just build a rough and ready bench from the cheapest structural timber you can buy from the local builders yard. If it is reclaimed timber or scrounged for free - even better. A large bottle of wood glue, a few screws, a drill, a saw and a screwdriver later you will have a bench more rigid than anything but a heavy duty custom fabricated steel bench. No fancy woodworking skills required and very light on the pocket too. You can make it as basic and functional or as pretty as you please.
If vibration is an issue, you can reduce it by using L brackets to fix the table to both the wall behind it (if there is one) and the floor at all four legs.
I made my main work bench this way and is way better than any of the purchased workbenches or machine stands I have. Don't omit the wood glue. It makes a massive difference to the rigidity of the bench.
