Thanks Jeremy, this one is definitely in my budget and it sound like a good idea. But looks like its strickly a Jeep product and/or requires welding it in place.
I was thinking more along the lines of this -

I was hoping to touch base with other folks who had used these to get an idea on how long they last. The air bladders don't look too beefy but what can I expect for a couple of hundred bucks.
