Buying a kindle to JB

Hello friends!

Looks like this question is more for this part of the forum..
I been following this forum for a few months and I finally decided to join to give a try a Kindle I want to mod
I have a Kindle KT3 up to date with FW updates and I know I cant jb that one easy
So before browsing eBay to get one to play with I wonder if can I get advised on what to buy (model and FW) to get what I just want
I want to jb a Kindle to get

6''
warm light and dark more (I can exclude this if I still get the others wishes)
Easy simple library collection that I can customize (not horrible Amazon order)
And most important, a easy way to plug a remote page turner, either wired or wireless, been reading of Kindle lazy but I got so confused on what to buy to mod for that

I know I could a kobo (clara possibly) and get all this, but I also doing this as an easy cheap project for Xmas

Advices, clues and recomendations are really apreciated

Thank you all!
