wow, thats wicked expensive for all that stuff. my friend and I built one, we were able to make a foot high, 10 ft long, 3pvc wide rail for $18, 10x3 piece of turf was $9, and the drop in was about $40 (6 feet high with a 3x3 platform up top, ramp is 8x3). Thats a sick setup tho, i love doing rails in the summer.
