I need cruise control.

Greetings,

I have a 2003 focus LX, it is pretty stripped down, just cd player, no power anything. That is ok with me (all I could afford at the time) except I am regretting not getting cruise control... Anyone have any recommendations... Aftermarket vs. Ford. Where would I get an aftermarket? Ford said they would have to put in a new steering wheel if I wanted the genuine ford cruise control and it would be $700.

thanks

Craig
