Monty,
Man, I thought that mine are heavy with the 2x4's, yours must weight a ton

. Bet they are solid as a rock. There is nothing like a good solid core door. I had used saw horses first and found that they were difficult to move if you needed to move the entire table. Building the 2x4 base is really easy. What is really nice is that HomeDepot will cut your 2x4's to whatever length you want. I really don't need a miter saw, so going to one in my area is great. I pick out the straightest 2x4's with the least amount of knots and then tell them what lengths to cut. I then go home and put together my table. The complete process takes about 4 - 5 hours from the time I leave my house, to the time my table is complete (now that I have done it a couple of times)
