I think I would build my own even if I could get them for $80. You would have about the same in them but if you get two sheets of plywood one for the top and one for the bottom you will have storage on the bottom one. Use 2x4's for the legs and frame you will have a much better table, also building your own you can get the right height that works best for you. I have my tables a little higher because I'm 6'3".
I wish I would have used screws because I'm about to move my tables to the new addition at my shop and I used a nail gun, my tables are 4x8 and the doors are 36". I never planed to add on to the shop so I was going to tare them apart when I rented or sell the building.
