You wont regret it, its super fun. I had as much fun digging it as i did riding it. You should ask @193kyle, he put a ton of hours into it. I think it took 10 or 20 yards of dirt. The shoveling isnt hard. I recommend the pump track ebook by lee mcormack. Too many people dont use enough dirt, and they put the rollers too close together. If you ever get a chance to ride a velosllutions pump track, do it!
