If that doesn't work out, you can always purchase a solid core door at a Home Depot or Lowes (preferably one damaged, so you can get a discount) and cut it to your needed size, and then make some table legs.
I fastened one to a set of trestle table legs and mounted a Dillon 550B, and have had no issues with it. I DID have to add some shelves the back of the "bench", and then load it down with cast pistol bullets (several boxes of 500ea. in .44 and .45) and it's pretty solid. If you don't load bulk pistol bullets, you could attach it to the wall. They are seriously stable..
Previously, I'd used an old lab table from a high school chemistry lab (yep it had gas jet and sinks, the whole nine yards) that I'd picked up for $25 or so. One heckuva deal, even in those days, but it had too much space and accumulated "stuff" to the point of clutter. It's best to keep it modest in size, so it doesn't take up needed space, and so it doesn't accumulate that "stuff".
