Pig Roast Rental Equipment

I was hoping to rent a caja china as buying one for $300 bucks seems a bit too much in case I decide to use other methods the next time around. Does anyone know or have one I can rent for a weekend? Thanks for the help, I live in Chicago but have a car and am willing to pick it up.

I don't know about rental, but there are a couple of threads about caterers who do this - they might be as good a place as any to start searching for equipment.

Whole Pig Roast or Lamb Roast - Roaster in Chicago ?
