Look on craigs list. Find one at a garage sale or church sale or the goodwill store. You can make one for about $50 but you'll have to maybe get the paddles and net for your birthday. you need one sheet of 3/4" ab plywood. Sand it smooth and paint it flat green. Use thin white tape to make the lines. You'll need a set of folding legs that you can buy new or may find an old table to take them off of. I think a regulation table is 9' x 4'6 or something like that, but a 4x8 sheet of plywood makes a good substitute.
