Honestly, there's no reason why you should have to pay for that...
I don't know about other guys around here, but it's pretty easy for my to find a free cabinet in good condition (without a monitor). I just give one of the local arcade distributors a call, let them know I'm looking for a cab for a project, and they'll let me come in and haul away an unused and non-working cabinet. Usually these distributors are just grateful that you're opening up some floor space for them and willing to haul away the cabinet.
