I've been doing a lot of searching on this subject to try and figure out what I'd like to do too. It seems that a lot of people either run the Sky kit or the ORD kit. I've read a ton of the threads on this subject and the only differences that I've been able to come up with is the customer services associated with the companies. I'm leaning toward the sky one (for hi-steer $675) just based on the price since ORD is $800. I've seen good things and people happy with both of the kits. I don't think that most of the kits actually come with the knuckles. From my searching, it looks like that would have to be something you buy seperately. If anyone has any input as to why you would use ORD over Sky, that aren't because of customer service, I'm sure we'd all appreciate it.
