^well thats only 10 feet...its teh longest i could get the pipes. so if u want a 10 foot flat (i also have one of those, but no pic) it would cost about the same. depending how wide you want it. you could make it a 2x4 on top with 2 pipes side by side, or 2x6 with 3 pipes, or just 2 but further apart. it would prob cost about the same, but maybe a little bit less. i didnt buy the materials for the flat me n my friend made, cuz i had some wood lyin around
