I like the link above:
C.C. Crow has a billiards table for $7.99. Looks pretty nice too. http://www.cccrow.com/
That's probably the best and easiest way.
I'd go to hobby lobby and buy some balsa wood, small detail parts and do it myself. It would be a fun small project. But again I admit...that link above is awesome. I had no idea that this was made.
