Throwing in my 1.161803 cents worth…
I went with collapsable, flip-up, casters along with leveling feet. Since my floor slopes, this allows me to position or rotate the entire table and return it to level quickly. I have found this combination works great for me and is very solid when the casters are in the up position.
