Confused Newbie! Help me with bagging.

[383drvr]

I've been toying with the idea of just going right to air suspension rather than spending money on a static drop. The problem is that I'm overwhelmed with the choices and varying costs for the setup. Is there an "Airbags for dummies" website or something that I can refer to? Depending on cost differences, I'd like to either go with just the basic and easy 4 corner, bags only setup, or to a 4 link with front/rear control. Can someone shed some light on what components are essential and how much I'm looking at spending for either setup? I'm sure this has been posted about before, but I havent been able to find any threads.

BTW, I've got an 83 C15 longbed. THANKS!
