<FONT face="Comic Sans MS">I the bought the Snake-Oyl cruise and installed it.
Though expensive and the only option I'm aware of, it's does seems to be a quality product. Directions are cobbled together and fairly weak though. Hopefully they've been updated since I installed mine. Also, the control module needs to be weather proofed as water can easily enter during rain or car washing.
You might want to try a search as I posted on it after my install.
