4" lift kit k20

[tinman_local2]

So I'm getting ready to order a lift kit and I was almost set to go with Skyjacker. I started looking around and noticed Tuff Country and Rough Country are quite a bit less expensive. I'm looking at complete suspension lifts(no blocks). Skyjacker is close to $1800 where the others are around $1000. My question is, is the Skyjacker really that much better? All have a lifetime warranty and come with all hardware and shocks, etc. Skyjacker does include longer brake lines. Can anyone tell me which rides better, better quality, or better warranty? Also, Skyjacker is almost a month lead-time, due to a backorder on front springs...
