Ron;
  I would try to salvage the original tops if at all possible, and make new moldings for them. It looks like the tops were some sort of walnut (either French or Claro) or mahogany, and the edge moldings were probably the same.
 As I mentioned before your best bet is to buy a second hand table saw off of craigslist or what not, if age isn't an issue you can pick up a fairly decent one that's 20+ years old, just make sure that it has a cast iron top and a decent fence/rail system.
 There is an easy way around the width problem on a table saw for cutting larger panels, you can build a sled out of some plywood with strips on the bottom side to fit into the T square slots in the top of the table as a guide. It's actually harder to describe then to build one.
