Well, somehow I fell down the rabbit's hole and now I've set my eyes on a CN 240mm gyuto. My previous knives were an Ultrex stainless santoku & cleaver that I bought off of Woot for $10 (haha) somewhere around 5-6 years ago. I "sharpened" those knives using some cheap little doo-hickey that I bought at the local supermarket where I drag the blade through a slot. I plan to use those knives to try and get the hang of sharpening before I attempt the same thing on my future CN.
But anyway, my real question: would it be money wasted to spring for a set of Chosera stones? I'm not against spending the $, but I worry a little that they would be wasted in the hands of a complete newbie. I saw that CKtG has a 1k/3k/5k set so I was considering that, or I could just get the 1k & 5k. The alternative would be a Bester 1200, and either a Suehiro Rika 5k or a SS 5k. (I'm thinking, also, that it might be smart for me to take the CN to be professionally sharpened at least the first time.)
Thanks all -- both in advance for any help you can render, and also to the larger community for providing so much information and guidance on the subject of knives (with a special hat-tip to BDL).
