Peter,
I have the EZ Electric PS system. Here's the link:

The major difference between this system and the SACC system is, it's speed sensitive, so the quicker you go, the less assist you get. In fact, the assist is gone by the time you reach highway speeds. Unfortunately, that makes it a little more complicated to install and a little more expensive.
