Best Leave In With KCCC-read posts and did not find answers

I went through about I think all of the pages of posts on [buylink=]KCCC[/buylink] and I did not see this question answered. If it has been I am sorry. I did not want to repost a question that has been answered often so I did try to search out the answer myself.

I live in FL, what is the best leave in for using with [buylink=]KCCC[/buylink]? Do others besides KCNT work well?

Here are the ones I see on the site that people use. Since you have to use a good bit of a leave in if I could get one less expensive than [buylink=]KCKT[/buylink] that would be great:

Giovanni Direct
Giovanni Smooth as Silk
CJ Assurance (think this is costly as well?)
Mixed Chicks (Think this is costly as well?)

Could you please recommend a light leave in that you use?

Also if you Poo can you tell me what Poo or conditioner you use?
