First of all, Hi folks. I'm a new user.
Just got a new '09 F-150 regular cab to replace my '96 150.
The 4X4 is a little too tall for my wife to get in easily so I'm lookin' for nerf bars. The OEM bars are way to expensive, so let me know what you think of the different brands. I've been lookin' at the Westin Signature bars, but if there is a better quality bar out there that is not tooooo expensive please let me know.

I cannot speak specifically to Westin's Signature series, but I ran a set of their Platinum series step bars for a few years with no complaints. They even withstood some additional four-wheeling abuse.

I think the main difference between the two lines is that the Signature step bars have a 3 year warranty vs. lifetime on the Platinum series.
