I ended up going with this type of design for my second machine. I made the table out of 1x1 steel tubing welded together. I did this after trying in vain to find a flat piece of MDF or wood. The table weighs in at around 20 lbs, so lift should not be a factor. You can also figure that the lead screw does help to keep the table down, depending on what you are using for a coupler at the stepper side. I guess I'll learn more as time goes on as to whether this is going to work or not.
