The first thing is do you want to sit or stand when loading. Be sure to get the height that is comfortable, So you can work efficient and safe. Make sure the table is stable and take the pressure of the press. A heavy top that will stand the torque a press will put on the table and top is a must. Make sure you have some good shelves to put tools and equipment when not in use near the table or above the table. Have enough electric outlets to run any equipment without chords in the way. If necessary put 3 or 4 receptacles in a panel board on the back of the table. Flexible lights, Lighted magnifying glass, Wall wart for electronic scales. Case prep tools. the list goes on for electric needs. A safe storage area away for the bench for powder and primers. A Steel plate 1/2 thick with holes drilled and tapped to match the bolt pattern of each press would be handy if you use more than 1 press. (Bolts straight from the top, No chasing nuts and washers under the table top. Take a look at some Carpenter Work Bench plans may give you some ideas. Good Luck in this project.
