For the Kubota supplied parts, 2 remotes (L8305/L8306/L8303/L8303) will set you back $1000 and 3 (add an L8307/L8303) will set you back $1400. The Hydraulic top link cylinder and the tilt cylinder with hoses (L8326) will set you back another $700. These are MSRP without installation.
The TCC setup which is essentially 2 remotes operated with a joystick, mounting hardware, hoses, top link and tilt cylinders will set you back about $1250. I am not sure if the TCC setup uses any of the Kubota remote parts but I think it doesn't.
