Can anyone recommend a source to rent one of these, preferably in the Arlington/Lexington/Waltham/Woburn area? I have had bad luck in the past using an under-sized rotisserie (the motor couldn't handle the weight of the pig), so I am looking for a large one this time. I don't care if the grill portion underneath in charcoal or gas. I have tried Taylor Rental in Arlington, and their units don't seem quite large enough. Thanks for any help.
