Inexpensive off the shelf bag kit?

[Skunksmash]

Hi all. I'm about to get my truck painted here pretty soon, and as such I want to continue on with getting the truck to look how I want. I don't know a whole lot about bagging. I assume you need 4 bags, air lines, an air pump, some wiring, and a switch to turn it on. That's about as much as I know. I don't even know what brands are considered "good" and which ones I should avoid.

Also I want the truck to ride much smoother, so that's a consideration. And if possible, I'd like to get a kit that allows me to return to stock ride height. I can't see where that would be a problem, if one were to simply select a kit that maybe didn't lower the truck quite as much, but the tradeoff was that it could still return to the stock ride height. Can someone help me out here?
