Now I realize you guys are arguing about YJs. They are an animal all their own, which are loved by the owners who found the benefits of their all-leaf setup. I personally am an XJ lover, who also owns a ZJ. I prefer the rear leaf stability over the flexy all-coil setup.
If someone came and offered me a JK for a price I could afford, I'd consider it...but would continue to pour the build money into the XJ. As it stands, I'm 10k+ into my XJ and I am pretty careful with what I do with it. But for 5k I could own my buddy's TJ on 33's and have a toy I'd be willing to tear up.
How many JK's have you seen rigged to the hilt, and said to yourself, "Man, if that thing was mine, I certainly wouldn't take the chance of wrapping it around a tree, or rolling it."
