Brian, I respectfully disagree. You're payin' almost a grand for a double bender, and you may have another grand in the guitar that you're supplying. A new D-10 Pro level pedal steel guitar is $4,000. 8 pedals, 5 knee levers. Go here:

click on the pics, and see what's involved in making a pedal steel. All very high precision parts, machined from billet aluminum, within 1/10,000 on most machined parts. Compare what you're seeing with a B/G bender installation. If these bender manufacturers/installers built a pedal steel, it would cost $50,000!
