Sawhorse will work well too. I've built a couple outta spare 2x4's and I bought the sawhorse bracket for about 5 bucks. When the guys at burro passed by I asked them about the bracket and they said they were cool about that. I guess it's because it's made outta aluminum and it's such area the likelyhood of it getting hit is small.
