For the legs, I had my hubby use the circular saw to cut off the ends of 2 of my other nicer pallets. I screwed them together then to the top. It was important to me to be able to move the table around easily in our living room (since it's really small with very limited space); so, I went to Home Depot and bought 2-2 packs of 2" wheel casters for about $12. Using a 5/16" drill bit, I drilled a hole in each corner for the casters and screwed them in.
Here are some pictures of the process:

Finished with the final coat!

And the finished product!
I must admit, I'm happy with how the coffee table turned out. It fits quite well in the room, it's mobile, and we can use the ends as little shelves; oh, and it's not heavy. :)
