This cost me about $500, but included some pricey tools.
It's about 12'L x 3W' x 4.5'H.
The top is 3/4" beech ply, the front is 3/4" pine board, framed on pine 2x4. It's built like a brick sh!thouse and has taken its fair share of beatings during parties. All the wood stained nicely and I threw about 4 coats of poly on it all.
I need to find some caps for the corners though. I think I may cut some 1/4 beech planks at 45s at install with finishing nails.
