I had 2 factory remotes installed on my machine. I thought about doing it myself, but it is not often in can be done better then the factory. The boys over at Kubota put some thought into how they put these machines together, and by the time you are done I would be surprised if you could do it for less then 700 bucks, providing all the parts are of equal quality. I see it alot on cars, and there is some ok aftermarket stuff for sure, but most of the time it is garbage. Just my thoughts. Good luck with whichever road you take, I will say I could not be happier.
