I fought the same battle you are right now... so many lifts, so many differences. What I ended up with was RE. I used the money I had saved for lockers to cover the expense, and I looked around until I found a good price. And I must say, I have had a LOT of lifts, different brands, heights, on anything from a 3/4 ton dodge to a 60's ford bronco, and the RE lift is absolutely worth the money. It's still brand new and very stiff, but the amount of flex makes it so I don't miss the lockers as much. I can't speak for the other 2 lifts, but the RE 4.5SF came with everything PERIOD no scrounging parts at 2 AM so I could drive it the next day. And that alone was worth the price.
Whatever you decide, lets see some pics when your done.
Here's mine RE4.5 33" tires....and it's gonna need a LOT more fender trimming
